Would really appreciate some advice. My 13 week old has alwayys been a good feeder, and has gradually increased his feed size in line with his weight (sometimes taking a little more than guidelines). At last weigh in with HV he was 12lb 10. Has started to decrease his feed size by around 100ml and I don't know why. He is regularly now short of the recommended amount of food for his weight (based on the 2.5 oz per pound of body weight) It is normally the midmorning or lunchtime feed that has become small. Is this normal around 3 months? Am worried he will start waking up at night again. HV suggested SMA white but I thought this was for hungry babies? Have also heard horror stories from people who wished they had not switched. Thanks.
