Somebody's sleeeepy

As I mentioned, El got her second round of vaccinations yesterday.  Obviously these have the benefit of immunizing her to certain diseases, but they have the potential for an awesome benefit to stay at home parents - a sleepy next day.  El tends to wake up around 7:30/8:00, and by the time Mom gets home (around 4ish) tends toward three or four naps.  Each nap tends to be just thirty minutes.  I actually have a working theory that her hour-long nap yesterday was simply an attempt to get out of going to the doctor's, as I actually had to wake her up.

Then we have today.  Today, El was awake for about an hour before she started to get tired, which is fairly standard, so I put her down at 9:15 in her pack 'n play next to the bed, and thought I'd have a nap myself.  I got up thirty minutes later, but little El decided she wanted to sleep until 10:45.  Needless to say, I was popping my head in to make sure she was breathing every so often.  But okay, her little body is working hard with those vaccinations, so it's bound to throw her off a bit.  Only an hour later she was ready for another nap.  Another nap that lasted an hour and a half.  At this point I'm figuring we're going to have a lazy day, so I'm not even surprised when she's ready to go back down around three, and didn't wake up until I was on my way out the door to work and Mom was home.  All in all, she actually spent more time napping than awake.  While I'm a little bummed we didn't get much time to hang out, a nice, lazy, easy day was the perfect way to end the week.  By the way, she's doing absolutely fine.  I had a report from Mom that she was super fun and happy while I was at work.  Which is good, because I'm sure Mom needed some fun El time after her long week at work.

Anyone else have a similar experience the day of or after immunizations?
