Guilt...

Today, Isabella and I didn't do too much.  In fact, we woke up very late (11am), had breakfast and went outside for a few minutes decided it was too hot so we barged into my neighbor's house as I know that at least one to three children, close in age to Isabella, would be there to entertain her.  We left about 2 hours later, sorry Clare, to come back to our home, have lunch, play on the computer then nap.
We are awake now, Isabella is eating Cheerios and I'm playing virtual cooking games on Facebook instead of actually cooking dinner.
While days like today are necessary, I still feel guilty that we didn't go to the park, ride the bike, walk more, color, paint, ect...
I sometimes feel like I need to entertain her constantly but I need "me time" too, whah!
I would like to know what other "real" moms do with their children.  I say "real" because I have seen my share of blogs that are possibly the reason I feel so guilty about today.  Moms who are completely engaging and creative.
Ugh!  I'd like to be that way but is that a mirage?  Can one really be that way everyday?
