We started out with two (twins) and lived in a smallish house in the city. We walked everywhere, went to the park everyday, the house was clean, the garden was weeded, then we got pg with #3, and felt like we needed a bigger house, bigger yard, better school system, closer to family, yadda yadda yadda. So we moved to a huge house, huge yard, great school system, close to family, and my house is never clean, the garden is constantly in need of a good weeding, we lack the $$ to pay for a cleaning lady, so I feel like I'm constantly yelling at the kids to pick up, never reading to the baby, never making a proper meal because I can't bear the thought of packing all three of them up and driving to the grocery store, let alone make it through the store without the requisite junk marketed to the kids (which we could do when we went to the market every day). And now with the older two in different activities, the youngest (who needs schedule and routine) rarely naps, and I'm finding myself longing to go to an office and leave the kids in daycare just so I can catch a break.
I love our children, but am really struggling to be the happy-adjusted-AP momma I was before #3 came along. I feel badly for her. She has some potential learning disabilities, so I beat myself up for NOT doing more for her to stimulate her brain, but with one extremely independent almost 4 year old, I find myself relying on "baby buckets" much more for her while I keep on top of DS. So I personally have a lot more guilt. When people used to say how hard they thought having twins was, I used to come back with, I have two arms, two boobs, it's not that bad. Now I have two arms, two legs (for lap sitting) and no space for baby #3 to even find a boobie.
Running errands is harder because I used to be able to hold hands, but now I need one hand to carry the baby, so someone always gets "loose" and explores. Which I'm actually ok with, until he wanders too far for me to see. It's harder to go to the park, as the baby can really only be in the swings, and the other two want to run in different directions. I also spend much more of my time monitoring what's been left out (in terms of legos) as babyproofing this go around is impossible. I just have to pray that I do my best and God is looking out for DD#2.
So there's the unvarnished truth from a momma of 3 who had a bad day. :LOL
Good luck with whatever you decide.
