just wanting to know if any of your babies have had bottle avasion so badly that they have ended up losing weight and if so how have you dealt with it? My daughter is now 7weeks old and has yet to put on even 1kg from her birth weight! Her birth weight was 3444 and she was weighed again today and she is only 4180 she has been this weight for around 3weeks now some days she puts on weight and other days she loses. I'm very worried and am not getting many answers from doctors. I figure mums know best so i'm hoping someone can shed some light on this.
