for DS3 (15 months).
He's into climbing and doesn't like to stay in his highchair for long when we're eating - instead wanting to climb onto the table.
However, last night at DP's - with the absence of a highchair/booster seat I saw him on the chair to eat his icecream and he sat there really well, obviously couldn't reach very well so made quite a mess but didn't try to climb onto the table once.
I'm wondering whether he wants to sit at the table like we do - and therefore wonder whether I should get rid of the highchair (had it 7 1/2yrs - since DS1 was 6 months old) and invest in a seat/cushion to fit on the dining chair?
