My little girl is almost 9 months old and I have just switched to a formula feed at bedtime (thurs evening).
First couple of days were fine then on Sat she was sick and couldn't keep anything down. She was fine between, just sick when she had anything to eat. Then fine on Sat evening, all Sun and Mon she was fine, then sick last night again with diarrhoea.
I am wondering if it is the formula? Although I was sick also on Sunday evening so it could be a bug.
Is there any advice on how long her tummy may take to get use to the formula?
