DS is a good eater, and a very good feeder (breastfed, never had formula). At his development check today the HV was concerned that he has only put on 4oz in 2 months, and is now on the 75th centile, whereas he's always been on at least the 91st before. However, he is only on the 25th centile for his height so I think he's just evening out. I can't be bothered with the expense and hassle of formula, and I don't like giving him anything processed TBH. But DH is more inclined to go with the health professionals on this one. Any advice would be really appreciated. Thanks.
