:hug: Miss X has been sick for ages and she has started walking, and she has continually been putting on weight. "Try" not to stress about the appointment too much, I'm sure they just want to check her over and make sure everything is okay.
Like the MCHN and drs always told me with P, DH and I aren't big people or have big builds, so P isn't going to be either and as long as they are happy alert and meeting milestones, it doesn't matter if their weight gain is rapid. Is X in proportion with her height and weight?
Also, a friend was told to give her 15month old sustagen (sp?) to help with her weight gain
