My son is covered in bites!

Samie

We let our son stay the night at his great grandmothers house and the mosquitoes are terrible there so we told her absolutely no outside time.

I picked him up today looking like this! She said they went outside for a little bit and he woke up like this.

The pictures are while he’s taking a hot (as hot as he can take it) bath and gave him Benadryl. What else can I do to help him?
