The 6 week check was the first time in 5 years I'd seen "my" gp, out practice just gives you an appointment with whoever is free, unless you specify (and A is just registered with the practice, not a specific Dr).
So far the hv said to talk to the Dr as it sounded as though he might have reflux, and the Dr wasn't bothered and just said the hv would monitor A's weight.
It's only because I wanted to see if he'd dropped more lines that I took him to be weighed yesterday! Otherwise nobody wanted me to bother until his 9 month check.
I want to keep an eye though. DH is fairly short, and was very small as a child. His parents refused to have the growth hormones they were advised to give him, so he may just be following in his dad's footsteps.
