It’s recommended that if they start to prefer solids to cut down on their solid intake and focus more on milk. If his soft spots aren’t sunken he shouldn’t be dehydrated, just keep offering water with food. Maybe you could speak to your health visitor if you’re worried for advice? Sorry if this isn’t much help 😅
Are you mixing any of his food with milk? You could mix rice pudding with his milk to give him some intake but I’d speak to the health visitor feeding team for support and advice and maybe cut down on the food and offer more milk again x
Personally I would cut down the food so he's more hungry for milk. Weaning to solids is to get them used to using their chewing muscles and hand eye co ordination, not to necessarily feed. Try not to worry about feeding baby too much solids as milk is there main source of nutrients until they are a year old 😀
I just thought that actually means my baby has had no fluids since that time so now I'm worried re dehydration 😩
