In my experience, it is tough going sure, but you learn to cope. I had all the negative comments, and still do and was absolutely terified I wouldn't be able to cope. I had no family around to help, it was just DH and I. We did cope and we did get things going and I even went back to work when the new bub was 3 months old. I look back now and wonder how I did it. I worked through my p/g too. I just used to do the bare minimum, DH helped out and I used to sleep when DS did, we often snoozed on the couch together! If not I used to lay on the floor and just lightly doze while he crawled around/on me. My whole point is that yes it will be tough but you will cope. Once routines etc. are established you just get on with life as you know it. I don't regret it at all now, my kids are great mates and most of the time they are happy to play together. To be honest I really struggled the first 2 or 3 weeks after DD was born but once I got my head around it all and got sorted we all coped much better! Follow your heart, if it's what you want do it. But a big pat on the back for stopping to think about it, I didn't! Good luck with whatever road you take!
