has your little one went off milk?

Kayley • 24 years old, I have a little boy who’s 4 and I’m TTC my second baby!! 👶🏻
My 8 month old drank 4oz of milk yesterday in total, he had about 2oz in his porridge in the morning and last night, so let's say about 8oz in total, I have no idea what was up with him, he was eating food no problem but just not wanting any milk, has your little ones done this?
