A 50-week-old baby is 350 days old — about 11 months and 15 days.
This week
Almost one! Standing alone and squatting back down like a tiny gymnast.
The math
50 weeks = 350 days ≈ 11 months + 15 days
A month is longer than 4 weeks — on average 30.44 days — so you can't just divide by 4. The exact answer shifts a little with the calendar, so for the day-perfect number, use the calculator with your baby's real birthday.
