DS is teething, has a cold, and is still having stomach problems...needles to say, he's not sleeping well, woke up so many times last night I lost count, he was inconsolable at some point, I think I got four hours (broken up) and he is so whiny now. I'm so short fused today, I snapped at him for getting into a drawer, and on top of that I have a little girl I watch two days a week for a couple hours, and she is getting on my nerves! This makes me think twice about wanting two kids

Ugh, ok vent over.
Re: Just one of those days...
Ugh, sorry
As for having two, the little girl would annoy you less if she was yours

I hope your little guy starts feeling better soon, though. Those ongoing stomach problems have got to be really discouraging :-(

Yes, fortunately "those days" are rare! We are both feeling better--mood wise.
The initial adjustment period for you may be a bit difficult, but I'm sure, just like we all did with our first, you'll get the hang of it, a routine of sort, no doubt. I have a friend that had her two LOs18 mo apart, and the baby's mid day nap lined up with her toddler's (around 1 pm) you might get lucky!

In the beginning baby will pretty much sleep all the time so there is a good chance you will still have time to recover or in my case take a nap. Around 2 month is when Audrey and Alyssa started alternating sleeping which honestly isn't a bad thing because it means I only have to deal with one child at a time. The two screaming babies and lack of sleep super sucks but happens so rarely that it is manageable. Good luck!
