Back to work / baby not sleeps

Hey girls!

So I had my beautiful little girl 10 weeks ago, 11 weeks Thursday and I go back to work Friday. Thankfully I work from home but my job is pretty demanding so my MIL is going to watch her while I work! Unfortunately I work later in the day (1:30pm-10pm). Recently she has been having such a hard time sleeping, she won’t take naps during the day anymore, or it’s really hard to get her down and she also hates her swing now. She use to love her swing and take naps regularly, this just starting happening a week ago. I’m extremely worried because I feel like this is causing problems with her and I feel like my MIL is going to have problems. Help?!
