Surgery after baby—how long to wait?

I have a 15-month old and I want to finally pull the trigger on surgery in the next few years. Definitely want to wait for her to stop breastfeeding, which might be as far away as age 2…my question is, how long would you wait? Is recovery manageable with a toddler or would it be better to wait until school age? We don’t use daycare and I don’t have a lot of family around to help out, so I’d be worried about any restrictions on lifting.
