Went to baby clinic today and DD has only put on 7oz/200g in a whole month. She is 6 months now and we started weaning at 5 months on advice of hospital paed as she wasn't putting on weight. Formula fed on advice of GP since three months.
Her rate of weight gain improved from three-four months, plateaued from four-five and is now decreasing massively again.
Feel crushed that weaning is making things worse- she only had fruit and veg and baby porridge between 5-6 months due to no dairy/gluten before 6 months but was still drinking the same amount of milk (800-850ml per day). I know fruit and veg aren't calorific (although we have given her lots of avocado!) which is why I have been working hard to maintain her milk intake so can't understand why her weight isn't going up. She fusses over drinking milk (since birth) and we absolutely cannot get her to take any more.
Plus she now has mild diarrheoa (I think nectarine is to blame) so getting even fewer nutrients. What am I doing wrong?
