A newborn sees clearly only about eight to twelve inches away, which is exactly the distance to the face of whoever is holding them. You are already in focus. By the end of the first year most babies are sitting, babbling consonants, responding to their own name, and treating you as a permanent retrieval service for dropped objects.
What they need from you: Your face, close and unhurried. And ask the parents how feeding is going, then ask how they are doing.
Month by month
What is happening at each age
22 developmental notes across birth to 12 months. Open any age to see what is typical and what it means for you.
1 week
Welcome to the gran life. Right now your grandchild sees clearly only 8 to 12 inches away, exactly the distance to a face holding them. Hold them close, talk softly. You're already in focus.
2 weeks
Newborns recognize the voices they heard in the womb, and they're learning yours fast. Talk, hum, narrate. The words don't matter yet. The voice does.
3 weeks
Tummy time starts now: a few minutes on a firm surface while awake and watched. Those tiny head lifts are the first reps toward rolling, sitting, and crawling. Cheer every one.
4 weeks
One month old. They're starting to study faces, yours included, and may turn toward a familiar sound. Slow down, get close, and let them stare. You're their favorite show.
5 weeks
Cooing begins around now, those soft vowel sounds are the first building blocks of speech. Coo back, pause, and wait. You're teaching the rhythm of conversation.
6 weeks
Right on schedule: the first real social smile arrives around now. Not gas. Not a reflex. A smile that's for you. Get 8 to 12 inches from their face and earn it.
7 weeks
Eyes are getting stronger, they can track a slow-moving object from side to side now. Move a bright toy slowly across their view and watch them follow. That's focus being built.
8 weeks
Two months. Head up at a 45-degree angle in tummy time, smoother arm and leg movements, and cooing back when you talk. The 2-month checkup happens now, ask the parents how it went.
9 weeks
This week's discovery: hands. They'll stare at them, bring them to their mouth, slowly realize those things belong to them. It's one of the first acts of self-discovery. Enjoy the show.
10 weeks
They're starting to bat at objects and anticipate routines, perking up when the bottle appears. Memory is forming. So hold this thought: they are learning what your arrival feels like.
11 weeks
Listen for it: the first laugh often arrives around now. It's usually triggered by something simple, a silly sound, a gentle bounce. Find what works and become the keeper of that joke.
12 weeks
Almost three months: pushing up on forearms in tummy time and recognizing familiar people from across the room. Yes, that means they can spot you coming. Make an entrance.
13 weeks
Three months! Reaching for toys, chuckling, sturdier by the day, and possibly working on the first roll. The newborn fog is lifting, and the personality underneath is starting to show.
4 months
Laughing out loud, rolling front to back, reaching and grabbing, month 4 is when babies become playmates. Hold a toy just barely in reach and let them work for it. Effort is the lesson.
5 months
Sitting with support, blowing raspberries, and grabbing everything, including your glasses and your hair. Sit them in your lap facing out: the world is the entertainment, you're the safe seat.
6 months
Half a year! Many babies sit briefly alone, babble consonants (ba, da, ma), respond to their name, and start solid foods. Ask the parents how feeding is going, then ask how THEY'RE doing.
7 months
Object permanence is dawning: things still exist when hidden. That's why peekaboo suddenly kills. Hide a toy under a cloth and let them find it, you're watching a mind discover the world is stable.
8 months
If they suddenly cry at the sight of you, don't take it personally. Stranger anxiety peaks around now and it's a healthy sign of attachment. Move slowly, stay cheerful, let them come to you. They will.
9 months
Crawling (or scooting, or rolling everywhere), pulling to stand, and a developing pincer grasp, thumb and finger picking up tiny things. The floor is now their kingdom. Get down on it with them.
10 months
Cruising along furniture, waving bye-bye, maybe playing peekaboo back at you. Imitation is the engine of learning right now, so everything you do in front of them is curriculum. Choose joyfully.
11 months
Pointing arrives, and it's a big deal. Pointing means "look at that WITH me." It's the first shared conversation. When they point, look, name it, and marvel. Every time.
12 months
One year old. First words, maybe first steps, both have wide normal ranges, so no scorekeeping. Their favorite game is dropping things for you to pick up. Congratulations: you are the retriever.
Gran Dates
Things to actually do together
12 ideas matched to this stage. Each one has a free version and a version worth spending on, because the free one is usually the one they remember.
1 month
Newborns connect through closeness and voice. Free: hold them and narrate a slow tour of the house, "this is the window, this is the kitchen." Treat: a high-contrast black-and-white baby book to "read" together at 8 to 12 inches.
2 months
Babies bond to the songs they hear repeatedly. Free: pick YOUR signature song and sing it every single visit, it will be yours together for decades. Treat: a soft musical toy that plays your song's lullaby cousin.
3 months
Face time is brain food at this age. Free: mirror play, hold them up, make faces, watch them study the "other baby." Treat: a play-gym mat for floor sessions where you're the main attraction lying right beside them.
4 months
Laughing games are connection gold now. Free: gentle "airplane" lifts and exaggerated peekaboo faces until you find their laugh button. Treat: their first outing with you, stroller lap around a botanical garden, narrated by Gran.
5 months
Everything is texture research. Free: a touch tour, velvet, wood, cool tile, your knit sweater, naming each feel. Treat: a crinkle-and-texture book set that becomes the official Gran's-house library, volume one.
6 months
Cause and effect is clicking: I do this, THAT happens. Free: kitchen-pot drum session with wooden spoons, messy, loud, perfect. Treat: a parent-and-me baby class (music or swim) where you're the cheering section, with the parents' blessing.
7 months
Object permanence is brand new, peekaboo is suddenly the greatest game ever invented. Free: a peekaboo marathon with a dish towel; hide a toy under it for the encore. Treat: a soft photo book of family faces, they're learning yours.
8 months
Movement is the project: scooting, rocking, maybe crawling. Free: get on the floor and play crawl-chase, "I'm gonna get you" is developmentally perfect comedy. Treat: start the zoo membership; stroller-pace animal watching mesmerizes.
9 months
Exploring containers and contents is the obsession. Free: dedicate one safe low cabinet at your house as theirs, wooden spoons, lids, treasures. Treat: classic stacking cups, the best dollar-for-dollar toy in human history.
10 months
Pointing and naming is how they map the world. Free: a slow walk where you point and name everything, dog, truck, tree, sky. Treat: an aquarium visit; the lights, color, and slow-moving fish are baby cinema.
11 months
Hands are getting skilled and opinions are getting loud. Free: ball-rolling games on the floor, back and forth is their first conversation in motion. Treat: a bookstore trip for board books of their very own, stamped "from Gran's shelf."
12 months
One year, start the tradition that pays off for decades. Free: the annual Birthday Interview: video them answering (babbling) the same questions you'll ask every year. Treat: a carousel ride, the first of many ceremonial spins.
Milestones are ranges, not deadlines. Everything here describes what is developmentally typical, and two children can reach the same milestone many months apart and both be entirely on track. Nothing on this page is a diagnosis, a screening tool, or medical advice. If you have a concern about a child, that conversation belongs with the child's parents and the child's pediatrician.
Rather not look this up every time? The Milestone Message texts you your grandchild's milestone as it happens, and The Gran Date sends one thing to do together on the 15th of every month. Both free.
