I dont remember what I did with ds1 (6yo) when he was a baby, but ds2 doesnt seem to show any interest in sitting on his own. He just sort of folds in half and sucks his toes :). He sometimes holds himself upright, esp if he's on my knee, but if I put him on the floor, he just wants to look around for something to hold, i.e. he isnt interested in "just" sitting (if I give him a toy, he just shoves it forward and leans forward again).
I am concerned that it's partly my fault - with having an older ds, we have a lot more "stuff" to do, and we are out and about more than I would have been with ds1. As a result, ds2 spends much of his awake-time in his pushchair, in the car, on his play gym or in a bouncy chair. He hates being on his tummy, so rarely has tummy time.
What do I do to encourage him to sit?
