This week
Almost half a year! Many families start planning first foods around now.
The math
25 weeks = 175 days ≈ 5 months + 23 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.
