There are a few of us pg w/ #2 right now so I'm sure you'll get some helpful info.
I am now 11 weeks pg with #2. I haven't been sick since I was pregnant with my son. Before having him, I was going into the hospital (and then home IVs) 1-2 times per year. My last course of IVs was when I was about 20 weeks pg. I have had some minor issues but no major lung infections (knocking wood!).
My lung function is the same as it was before I had my son. My FEV1 is in the mid 60s and has been there for a number of years. Taking care of my son as a baby was a piece of cake but taking care of him as a toddler is a different story! He has opinions and likes and dislikes and is VERY intense. Being his primary caregiver since my DH works means that I don't always get 2 treatments in per day. I can almost always get my evening treatment but the morning treatment is iffy. If nobody else is here to distract him and he doesn't want me doing the treatment there isn't much I can do about it since he can turn off the machines or he will cry and scream the entire time. Not really worth the fight IMO. I'm sure it will get better as he grows and matures. We're just in a difficult phase right now.
We waited till my son was 2.5 before trying for #2. Knowing my son's personality, having a baby too close in age to him would have been a nightmare for me. He will be 3.5 when the new baby arrives and I'm really hoping that he can accept the role of big brother without too much struggle. I'm still really scared about it though.
If I were in your situation, Joy, here is how I would go about deciding #2. Is it likely that you will deliver prematurely again? If so, is there a chance you could end up in the hospital (or home) on bedrest? Who will care for your daughter in that situation? How would she handle being separated from you if you end up in the hospital due to complications. If you deliver early again, will you have care for your daughter so you can take care of your new baby in the NICU? I know in my situation, my son would NOT handle being separated from me well at all (and I would be equally upset). As it is he gets anxious and upset if I'm gone for more than an hour or 2. But your daughter may be totally different so just some food for thought.
Good luck making your decision <img src="i/expressions/face-icon-small-smile.gif" border="0">
