your babe sounds normal, your hv, in my personal experience sounds pretty normal too.
sometimes they talk absolute crap.
both my kids were huge at birth. ds1 was skinny and long though and still is but ds2 is a little porker. i dont take him to clinic.
if she wants to see him, she rings me and then i take him down.
i have been told ds2 needs a 'diet', i was told ds1 was a bit 'abnormal' as he never crawled, he just got up and walked, i was told i had to do cc if i wanted a normal life, was told bfing didnt matter....
those few are my persoanl favourite corkers...
