Has anyone started sleep training yet?

I’m not sure if I should start already or if it’s too early. My little one is 10 weeks old. I’ve been trying to transition her nap times from her boppy to her crib but that has cut her naps down to 20 minutes. She will only nap for 20-30 min in her crib before she wakes up. On her boppy she will sleep over an hour.

Just want to know what others are doing in regards to sleep training and how long your babies are napping throughout the day.
