Thank you both! I've been wanting to cut out the milk she's been demanding in the night but although I was pretty sure it was habit, I was worried she was asking for it to keep her levels up...
She's drinking about 5 - 700ml per day as well as what she has on cereal She also has plenty of cheese and youhurt too so she's definitely having enough.
We went straight over to cows milk too MrsJamin. I can't believe what a palava it seems after BF, messing about with bottles and remembering to take it with me to bed etc etc.
