I Have a 3 year old son who will be 4 this October, I feel like I want another baby but then get filled with dread when I think about all the lack of sleep and having to go through the terrible twos etc... what do people think is a good age gap? I know if I had one I'd manage as I'd have to. My son sleeps through but gets up between 5-6am. I'd be doing on my own. As me and my partner love seperatly due to him having 3 children from a previous relationship and our kids going to school/nursery 30mins from each other.
