My 28 month old daughter has recently taken to sitting on my knee watching tv or listening to stories for anything up to 1 hour at a time. I put this down to the fact that I was off work for the last 5 weeks and she missed me!! But now she has started to do this with my mother who cares for her whilst I work. This is making me question could there be something else wrong (medical/emotional). Apart from this she has an excellent appetite and when she does play is as lively and noisy as the next child. I would be grateful for an advice or stories of similar experience - before i turn into paranoid mother thanks!!
