cat napping

Danika • First time mom to a beautiful baby girl 👶🏼
My baby girl who is 6 weeks ,  went through (what I think ) a growth spurt two days ago. For two days she ate and slept long hours. Today though, she just can't seem to sleep,she only did two naps today and that was at 11am, she slept aprox. 1 hour. And again at around 7;30 pm for another hour. I've been trying to get her to go down for the night, been trying since 9pm, she only sleeps like 15-30 mins and then is up again. What do I do?
