L.R.
I can relate. With my first, I was sick the entire 9 months and was hospitalized throughout most of the first 5 months. So, even though my desire for a second child was very strong, it was tough to think about being pregnant again.
This last pregnancy was much better! I had to be hydrated twice, but other than that it went pretty smoothly. Memories of my first son's precious face were enough to keep me going through the second pregnancy.
A few words of advice: 1). Get someone to help with childcare. Even if it's just a teenage helper, she could play with older children while you rest. 2). Keep emergency numbers up on the fridge in case you're feeling really lousy. 3). Stock up now on gatorade, popsicles and italian ice.
Anyway, good luck! I hope you have some happy news soon:)
