I started preschool with DD1 right after she turned 3. DS was 11 mos and I was pregnant. We mainly did/do letters/numbers, crafts, sensory activites, etc, so nothing major. I used to prep after I put her and DS down for bed, and we did school during DS's nap. However, I have a 1.5 y/o and a 2 m/o now and I'm finding any time I have left in the evening goes toward sleeping. How do you prep, let alone have time to "teach," when you're up all night with babies and don't have more than a few seconds here or there during the day without a child in your arms?
