Dd is 6 months old and was very sick last night. At first I thought I had overfed her as I woke her at 11 before bed (as usual) for her last feed but she seemed fussy and disinterested. She did take some but was then violently sick and had a really explosive watery poo which required a total change of bedding and clothes.
She slept after that for about 5 hours until her next bottle in the middle of the night as normal. She had this and immediately had another episode of diarrhoea afterwards. Not as much as earlier and no sickness this time. She's woken up in a happy enough mood but I'm worried about dehydration if she's unwell again after her morning bottle. I've never had to deal with diarrhoea in a baby so young before. Any advice appreciated.
