Any advice?

I've been thinking of leaving my job to stay home with my kids. With covid, everything is so strange. My daughter is in first grade and doing everything online. I also have a two year old who hasn't been anywhere (besides my moms house) in months. I work part-time as an aide at a school. My mom luckily left her job over the summer to stay home with my brothers. Her husband makes good money so she really wanted to stay home after working over 20 years as a single mom for us kids. I was thinking of leaving my job. I am thankful for my mom but she can only do so much. She makes sure my daughter gets on her zoom and does her work but she has my brothers and my little one to focus on as well. I was thinking if things aren't back to "normal" by December, I would resign and that would give the school winter break to find my replacement. My husband said if I want to stay home, I could but he would need to find a second job. He makes decent money with his full time job but I pay about $500 in bills and $400 for groceries while he pays rent, car, etc. We could do it, I just don't want him to resent me. I also don't want to regret leaving my job but I want to be there for my girls. I want to help them and make sure they're eating healthy meals instead of what grandma gives them because they're here grandchildren. I also know how scary and strange this all must be for them. I am conficted. Should I leave now or wait it out? Idk. I have a lot to think about.
