Myself and SIL both had babies a few days apart,who were the same weight,they are now 7 weeks. SIL and MIL seem obsessed with giving her baby and consequently my baby water.
I was bf-ing up until a few wks ago and her baby has been formula fed from the start.
They ask me every time I see them do I give my baby water and each time I reply saying babies don't need water unless its really hot outside as they may be more thirsty, as mw and doc have told me. MIL has told me she has given my baby water on the 2 occasions she has kept him- even though is wasn't warm and she knows i dont do it.
Every time I see SIL she is either giving the baby water (3-4 oz) or telling me she gave her water as she was crying but isn't due her feed yet. She says her baby goes 4-5 hours between feeds but she gives her water between them to hold her out.
This would not bother me as much only her baby is a hell of a lot lighter than my baby who I have been told probably should be a bit heavier. I lifted her the other day and was really shocked as how light she was, didnt feel much heavier than our baby's birth weight at 7lb 2oz, my baby is 10lb 3oz now. Her baby is also doing 4 or 5 dirty nappies a day, and SIL is saying she has diahorrea because she is teething, im thinking it may be the water.
The health visitor has not been to see her since week one for some reason so her baby hasn't been weighed since then.
So AIBU to be worried about her babys weight and possible lack of nutrition, and frequent dirty nappies or is this normal?
We are both first time mums so neither of us are experts I'm sure, so would appreciate some views from mums.
