Re: weight gain
IMHO, if there is nothing IN ADDITION to weight gain that is of concern -- refusal to eat, swallowing issues, sleep issues, low diaper output, developmental delays, frequent infections, low energy, etc.-- it is highly improbably that there is any problem.
Typically, doctors like to see babies stay on their own particular growth curve, and get concerned if they drop off of that curve over time without an obvious explanation. The concern is basically valid, in my opinion, but it needs to be taken in the context of all that is going on with the individual child. If there is no other concern at play, there doesn't seem to be any reason to do anything except monitor the situation and know what to look for by way of symptoms of specific reasons for added concern and action.
Do you have any concerns about anything else going on with your little one? What is your gut feeling about it?
