so ds had his check up today. he is 4mos and weighs 13lbs. Birthweight was 6lbs. 10oz. so i thought we were doing quite ok since he almost doubled his birthweight. Anyway doc. is a bit worried since he is in a low percentile for weight 15th i believe and head he is in the 4th, for lenght he is in the 35th. Anyhow we are all kind of petite. the problem is really that he doesn't nurse for very long 5-10 min max and only on one side. so i'm worried about him maybe not getting enough hindmilk. How do you know when they are getting it. does it come after the first letdown already? He is pretty much done feeding usually always right after that. I nurse one side each feeding and i block feed if it was less than two hours since the last feeding. i don't think offering both sides or switching more often would help in terms of him getting hindmilk, right? he poops once a day always yellow but very liquidy, not seedy. and urine output seems fine too. what do you all think.
