Just wondering if there's anyone who uses this formula that can help. I want to make sure I'm giving my DS the right amount. DS is over 2 months old (10 weeks) and I am going off the tin and giving him 180ml 5 times per day. The tin specifies 'up to 2 mths 120ml' & 'up to 4 mths 180ml'. I am concerned because the common formula of 150ml x kilo of body weight divided by number of feeds works our to be a smaller quantity. I'm concerned I'm over feeding my DS, although he is finishing the bottle. What do you think?
