This time round, my husband has booked him in for his next round of vaccinations (4mth ones). My question is, he will only be 14wks & 5 days. Will they give them to him or do I have to wait until he's exactly 16wks or 4mths according to the date he was born (he was born 29th March, so would I have to wait until 29th July?)
From past experience they wont give it to him until the 29th July, 'they' work in calendar months.
