20 month sleep regression?

My daughter has slept well her entire life until now. She is fighting sleep and wakes up at 2 or 3 am wanting to play or cries to come into our bed.

Sometimes she takes forever to settle, crying for over 30 min before she will go down.

I'm currently watching her on the monitor at 4am crying for mama and dada "up".

Any advice on whether this is a phase or did I just have it too good 😅
