My HV just told me she was really surprised I still gave DS milk sometimes in the night. We do this sometimes to settle him. Hes not an awful sleeper but not the best either. Normally sleeps 11 hours ish. Sometimes sleeps through, but often wakes (about 50%) of the time wanting milk, once in the night. I just give him it for an easy life. Although know that one day we might have to try and wean him off it.
But surely there must be loads of other 2 year olds getting milk in the night still? I can't imagibe we are that unusual.
