This may sound like a really silly question but do I need to do anything to encourage my little boy to sit and eventually sit unaided? He's 17 weeks old and will sit on my knee or on the floor between my legs. Sometimes, he will sit/slouch for 5 minutes in his highchair while I make toast/tea etc but is this something that they will do themselves in time or should I do anything to help?
He still spends quite a bit of time on his back on his playmat and is making attempts to roll over now. Quite happily lying on his side.
He hates going on his front though.
