DS2 was born at 35+5 on 25th pc for weight for a baby of that gestation. All the further ages I'm going to give his adjusted age (and then his chronological age in brackets) as it seems all the HCPs use his adjusted age. Anyway, by 2 (6) weeks he was on 50th pc, and he stayed there until 28 (32) weeks by which time he was on the 75th pc and we had started weaning. Now at 39(43) weeks he is just above the 91st! The last weigh in was at home (i got on the scales with him, then weighed myself alone). My DM says he looks fat, but I think she's just forgotten what babies look like. He does seem to fill his (sized 6-12 and 9-12months) clothes lengthwise, so I get the impression it's not just fat but length growth too.
He's a good eater, and actually eats far more home cooked food than DS1 ever did, and less puree, more proper solids. I also have tried to learn from my mistakes with DS1 (a whole other thread), and stop offering him food as soon as he refuses.
Do I need to speak to the HV? I've not had his length measured, and I'm not sure they'll do it even if I ask... DS1 was 2nd pc at birth (39 weeks) and rapidly got to then maintained 50th pc thereafter. DH is slightly taller than average at 6ft, and I am short 5ft1. Build wise we were both skinny kids but are average now (13st and 8.5st).
