It could be, depending on other factors, but a doc would need to talk with ehr and decide that. However, she is grieving. Everyone grieves differently. And a child is a small person. She is trying to be strong for you, but she is still a hurting little girl.

Maybe color with her and just chat. A child will normally open up when not pushed or feeling threatened in some way...like worrying about hurting you. Maybe share with her your sadness or how it is ok to be sad...if she opens the topic. Maybe go for ice cream or something she enjoys doing. Just be there for her.

Not sleeping well makes anyone irritable and snappy. It is no different with a child. Maybe find a child T that can be an impartial person for her to open up with.

Everyone deals with grief at their own pace too. It can be delayed, as in 8 months later. That is not uncommon. Children often grieve through play, so that is where I would start. I would find someone for her to talk with adn play with her. Uninterrupted playtime with just the two of you. Maybe find a childrens book about loss and grief and read it with her.

It may take more than one attempt, but let her lead the conversation. Let her express what is stressing her. Love her and let her know you are there for her.

I hope this helps in some small way. Good luck.
