feeling guilty doing stuff for myself

Hey ladies first time mom to a beautiful 11 week old boy here. Well my maternity leave is slowly coming to an end. 😭😭😭 I go back to work on January 3rd after Christmas break (I'm a kindergarten teacher). Anyway, I figured I should try to make myself feel presentable before I go back so I got a mani/pedi on Tuesday night while hubby stayed home with the baby. Last night I got a facial (had a certificate to use that was going to expire) and tonight my friend sara who is a hairdresser is doing my hair (haven't had it done since before I was pregnant!). Anyway I'm feeling super guilty for doing these things for myself!! Probably because I haven't dont anything like this for myself in 9 months and also because I hate being away from my baby at all. But I figured it would be best to get this all done now since next week is our last week of being together 24/7 before I go back to work, and I definitely won't want to leave his side at all. Anyone else treat themselves to looking a little nicer again and did you feel guilty too?
