Early 3-4mo regression?

Victoria • Mother to a baby girl born in 06/2020! 🎀

My LO is 12 weeks (3 months next week) and has all of a sudden been taking no more than 20 min naps and waking up 2-3 times in the night. She was so good at taking 1-2 hour naps and only waking 1x at night up til this point.

Could this be an early 4mo sleep regression? Anyone else experiencing this? She is going through her third leap.
