Sorry if this is long:
My daughter is 3 weeks old. She has transient hyperthyroid, where one of the symptoms could be lack of weight gain even if she is eating a lot. So far she has not demontrated any symptoms and this should clear her system in the next few months. She initally gained well, but then lost, but only 1 oz. She then proceeded to gain well again.
She used to nurse from both sides. Now, she nrses from one side. I overproduced with my 2nd child and I thought I was seeing signs of this again. I'm not sure though b/c it's not as bad. Anyway, she is also very gassy, so I thought she was not getting enough hindmilk. She will usually nurse 10-15 minutes, then fall asleep. I will change her and then put her on the same side. She then nurses again for maybe 5 minutes.
I am just really nervous about her not gaining weight again. She seems content afterwards and will sleep for a few hours at a time. So my question is would I know if she was not getting enough? Would she show signs or protest? Should I try to feed her from both sides?
