Age - months or weeks ?

[Hunnybunn72]

How do I work out when my baby is 6 months old, is it 24 weeks or the birth date in the 6 month ?

6 months is half a year, so it is the date your baby was born + 6 months (i.e. born 3rd September, 6 months on 3rd March). A month is not 4 weeks!

6 months is 26 weeks which is half of 1 year (1 year = 52 weeks)
