I know its going to be hard and i'm sure i'll be on here from time to time looking for suport and sympathy but people cope with twins / triplets etc so it must be possible.
Of course it's possible, you only have to look at Sarah who is going to have 5 under 5's to know that lol.
You do sound like you have a supportive DH, will he not be posted away? I know some friends of ours live away with the RAF and her DH used to be posted away for weeks at a time.
I guess we're all just being honest and trying to warn you that the reality of having two so close together is hard work. My DD was very well behaved at your DDs age although that started to change when she got to 8 months. I remember crying to my DH during the first tri that I'd made such a massive mistake as I was exhausted, felt constantly sick and DD was being a nightmare to deal with.
There are good times, like when DD and DS will play together for a couple of minutes. Or when DD gets up in the morning and just wants to give DS a hug.
Just on another note - I thought you had to wait a year after having a c-section before getting pregnant again?
And on another, I'm sure that because I got pregnant so soon after having DD that my body hadn't recovered enough to support my pregnancy (I bled, DS was 4 weeks early and I had SPD) and for all my stores of nutrients to be there for the baby. DS is very sickly, despite being breastfed and is also asthmatic. Obviously I blame myself for getting pregnant so soon again. If you are determined to ttc now then make sure you're eating well and start on the folic acid before you start ttc, you need to get your body into tip top condition.
