Your daughter is very young. You may want to try keeping her home with you for a couple of years & forgoing playgroup, and seeing how that works for you. That may give you an idea as to whether homeschooling suits you & your family.
I do keep my children home with me until they are 4 or 5; they socialize by playing with their siblings & neighbors, and start school in pre-kindergarten at around age 4-1/2. This has worked well for us. Even if you don’t choose to homeschool there are many ways you can supplement her education at home after school & during the summer.
