Feeling like a failure

I put on Ms Rachel for TWO hours tonight … my twins are only 9 months old. My husband is gone on a work trip and their nap was absolute shit and they were screaming from being over tired. I don’t ever know what to do with them. It’s 103 degrees outside. I can’t do this without my husband or my mom helping. Please tell me other people have used Ms Rachel for that long?? What else can I do with them aside from throwing toys in their face
