@Holly my twins are exactly the same as this xx
Dietician said 600ml per day minimum to me also. My girl currently has 4 bottles so has around 650-740ml per day. She does have 3 meals but she doesn’t tend to eat very much for lunch at the moment
I was advised by a dietician when I was seeing her about allergiesl that they should be having roughly 600mls a day. My girl has 210ml X3 a day and 3 meals and a mid morning snack a day ☺️ all babies are different though I can't see all babies fitting in to that exactly. But that's the guidelines I was given ☺️
