Moms with three under three

Okay a little bit about me I'm going to be 35 this October I have a baby a little over two years old 27 months to be exact and I have a little man who just turned 5 months old on the 30th I'm lucky I got a girl and a boy so I'm blessed there I keep wanting another baby and I don't want to wait too long being that I'm going to be 35 some days I want another one because I just want them to have more of each other as they grow some days I just want the two I have because it's hard enough so I'm just curious how is it with 3 under 3 pros and cons I know the hard times don't last forever part of me wants to start trying for my last baby but another part of me is saying don't even go there LOL it's a Bittersweet situation any feedback would be awesome thank you little ones just to show off
