Haven't seen many. I have to be in the mood to be able to enjoy it. But the ones I haven't seen mentioned are

Kimi Wa Houkago Insomnia

Itazura na kiss - oldie but good

Kuzu no honkai - romance but the bad part of it, unrequited love. I really liked this one.

Probably the child bump into an adult, fell to the ground and hit his/her skull too hard.
