Health or sanity help

My husband works an hour away and leaves around 930 and will be home by 730 8.. I am currently working from home 730 to 330 with a 3 year old and almost 3 month old. She does not like to nap too much during the day. Is there a way to get her to take longer naps? I am losing my sanity and virtual pre k is about to have longer hours next week. I cook, clean bottles, laundry, try to go for walks for my 3 year old and I am exhausted!! By the time my husband comes home I’m pretty overwhelmed and tired. I will explain that it’s hard but I guess it comes off as an attitude. I don’t want to have an attitude.

Any suggestions on how to make my life easier? I just wrote down 21 meals to that are “easier”
