I introduced 11 week old babs to formula to top up on thurs night coz her weight was low. She weighed 11lb 8 half at birth. Her weight went right down ,and has now climed back up since i did this and changed her feeding pattern (3 hourly).last week she weighed 11lb 7oz this week she weighed 11lb 15oz.BUT she hasnt had a poo since fri morning and its worrying me a bit.HV advised me to give her 2 t spoons of water and 2 t spoons of fresh squeezed orange to help her bowels empty??? Will she weigh a lot less wen she finally passes 1? HV said its quite usual for some babys to go up 2 4 days without passing a stool,tomorrow will b the 5th day.Has this happened to anyone else and has anyone got any advice ??? also ....... babs was on the 98th centile last week and is now in between 50 and 25 wat does this mean?
