DD1 (4 in March) is allowed to watch a show or two (depending on their length) during DD2s naptime (don't want DD2 exposed to TV just yet as she is only just one today plus keeps her quiet while I'm settling DD2). I'd say she watches something half the time, half the time she prefers to just have a more quiet play in her room. She always turns it off when told though so hasn't been a problem.

Very occasionally if DD1 has had a late nap (she doesn't usually nap anymore) because we have been somewhere like the coast for the day, I will do her bed routine at the usual time but then leave her with a movie/show on the laptop since I know she will most likely be awake a little later and if I'm on my own (DP works late sometimes) I need her to at least be settled while I put DD2 to sleep. This would be once every 2 months or so though. We have also done this once when she was feeling sick and just wanted a rest, I put it in her room again because of not wanting DD2 exposed.

That being said I was similar late in pregnancy with DD2 because it was soooo hot and this continued a little after DD2 was born whilst we got settled. It was easy to change though once we got through it. I'm really sorry to hear about your stillbirth, that must be really difficult. If you need to rely on TV a little more just now, there are worse things
