I'm kinda in the same boat. I am in a distance grad school program. All online! And everyone says "oh, you can do all the work when your toddler is sleeping!" Which isn't that helpful. There is more work to do than napping that will happen. And toddlers this age tend not to sleep so well at night, so I'm tired and getting work done at bed time doesn't really work, either. Then there are the other things that we sometimes need to do when toddlers nap. Eat, shower, clean the house, make phone calls... I have figured out, for me, that doing work with the toddler around just doesn't work. It makes him grumpy, it makes me grumpy, and not much work gets done. A babysitter or daycare would be the best option... if it was not so expensive, but it is. If you can't swing it, maybe you could find another mom to trade babysitting with? Or, if you are partnered, your partner can watch the baby while you get work done?
