even if I was up for an hour last night at 2AM because my toddler can't pull the blankets back on him in the middle of the night and fights me when I try to do it for him.
Oh thank god my kid's not the only one. He hasn't slept through the night more than a day at a time in almost a year, starting at around the age of two, because he apparently decided then that having his blankets come off was a reason for terror, and can't yet get them back on himself.
But to answer your question, Catwoman... the first two (step)kids were part of the package in marrying my husband, and I decided I wanted the package.
The additional kids (which so far do not exist but we're working on it
)... well, like glatt, I always knew I wanted children, from a very young age. The ability to teach a child everything you know, and the reward of seeing a happy child, I think are the two things that appeal to me most about it.
Some people (especially women) get off on having something that "needs" them, and they are usually disappointed when their child eventually becomes their own person. For me, it's the whole timeline that appeals to me--I like the idea of having Christmas when I'm 70 and having all my children bring their children to the house, just as much as I like the idea of teaching a baby to walk and speak.
