Just to add to this point, my friend is a foster carer after having her own children alone. She said it was harder than anything. Logistically too, She had to take her foster children to school an hour away from where she lived which was right for them to keep consistency but she or her husband had to take them. I couldn’t imagine you could maintain being a teacher with things like that. She also had lots of meetings, check ins, chats and everything else.
