Interest... I have two small girls, 3.5 & 2 in May. They both love to watch tv, to have some relax time. Or a Disney DVD. Or the gruffalo.
The only thing I've noticed is that my younger dd seems to have her own routine of when we get back from school drop off she will ask for the gruffalo. Or various Disney DVD and I'll offer to do reading! or playing but then she sometimes would prefer a DVD.
In the morning dp puts peppa pig on whilst he's getting ready for work (6am) they wake up with him whilst I'm feeding 6 week old.
Sometimes I find it beneficial as they do enjoy the down time. But then I think they just expect it all the time some days?
