Not sleeping till late 😩

A Marie • Liebe besiegt alles. 🔜 to be Mrs. Manson Amelia Mae 🎀

My daughter will be 5 months on the 28th of this month. I thought we finally had a sleeping schedule down till she threw a curve ball and now doesn't sleep till 1 a.m

I try keeping her up but she takes an hour nap @ 8 then goes to bed at 10 and then wakes up wide awake at 11 😩😩😩 how do I change this? I'm also 14 weeks pregnant and definitely don't have the energy to be staying up this late every night with her. Any advice would help!
