I'm prone to hairpulling and nail biting myself, so I'm pretty sure it's a response to stress and social isolation and lack of intellectual stimulation and lack of routine. I can't be everything for her.
We decided not to send her back to preschool in the fall because seriously how the fuck are preschools opening up again? 4-year-olds are not going to socially distance or wear masks all day. We have people in their lives, but they still need a lot more than we are capable of giving them.
I know it's hard. I've had to give up everything that is for me. We have 4 kids and they need 200% of our attention to keep happy and socialized. The 3 and 1 year old at least play together, but it is a lot of effort to keep them all engaged and not just giving in to turning on peppa pig.
This situation sucks, we recently gave up completely avoiding the outside, we had to check our a zoo and hit the playground recently to give them something.
My go to has been sesame street record sing alongs, and puzzles.
You just started going outside? Damn, I've been taking all my meetings on stroller walks
