OK so we had yet another carppy night! Is it possible for a baby to go "off" a formula??? She was on S26, then NAN then NAN HA and now she takes about 60 ml of a bottle and pulls of screaming! SHe gets burped and plays for 10 mins and as soon as I out the bottle in her mouth she screams again! This has been happening all night! 60 ml at each feed is not enough! I am scared she will start losing weight - she seems happy otherwise though so maybe it is enough for her? She slept from 9 uintil 2 and then until 5 this morning when I bought her into bed with us and kept her there till 7. I am going out of my mind!!
