When I started homeschooling, my children were 2, 7, and 9. That wasn't hard because I had a very easy toddler. When my third son was starting 1st grade, though, we had added three more through birth and adoption. Schooling a 1st grader with an infant, a 9mo, and a 2yo, while also trying to have some time for my 12 and 14 year olds wasn't so easy! To be honest, that year is a blur. We got through it and it got easier every year after that. Whatever the age gap, you just have to learn to juggle your time. You'll do fine.
