Ds4 seems to have gotten heavier since starting solids 2 weeks ago....

[chipmonkey]

But he has hardly eaten anything! A few bits of broccoli, bit of carrot, bit of fruit, bit of porridge, nothing at all calorific! But he derinitely feels more solid! Anyone else found this? Or is it just coincidental?

coincidence. there's a 6 month growth spurt if he's around that age.

Yes, he is 6 months. He had seemed to level off for a while before that, so maybe he was just due a growth spurt!
