We have all had those days! If his levels are good his CAH is in control and all the height and weight issues will even out as he gets older. My second SW CAH’er was so small, not at birth 8lbs+, but he did not grow much and did not gain weight, it just drove me nuts with worry. He was tiny. He is 5 now, still smallish, but just a ball of fun and fire. Try not to worry and enjoy your son.
On his one year check-up, the nurse wrote done 0% for height and then crossed it out so I wouldnt feel bad.....I just thought Oh, if you don’t write it down it is not true? I remember just feeling bad and mad etc....and now it just makes me laugh. It is easy to look back once you see the kids they turn into. Hang in there as it does get much easier.
