Ds is 7+1 and is taking a variable amount every time he wants it. He can guzzle 180ml every hour and a half or the same amount every 2-3 or 80ml every hour if that makes sense? He is all over the place and as I have dd 18ms and dd9 at school (school runs) I really need to try and establish some kind of routine as tbh I feel as though I am losing the battle here. I really need some good advice as feeling like a bad mum atm
