Crap Naps (10 weeks)

Hi! Struggling with my LO and daytime naps. She will be 10 weeks old tomorrow and her wake windows right now are roughly ~75mins.

When she contact naps, I can get 2 hour naps, however, as much as I love snuggling, it’s not sustainable. I go back to work in 4 weeks and my parents will be watching her some of the time. I work from home, but still need to be productive during the day. When I put her in her crib, she only lasts 20-30 mins MAYBE (and that’s after rocking her to sleep for 15/20 mins). Any advice here on how we can lengthen these crib naps or is this just how it will be until we sleep train at 4 months?
