I don't know how they do it

Moms with big families that is.  Last week a friend of mine asked me if I wanted to join her on a trip to the Baltimore Aquarium. And while we had a great time I found it but a bit stressful at times too; see we had five kids and one on the way (she is 7 months pregnant) between the 2 of us.  Add in a couple hundred kids on school trips and wow did we have our work cut out for us.  Keeping an eye on 4 kids going in opposite directions can be really tricky and I must say I did not see much of the Aquarium as I was too busy watching out for our little ones.  How do moms with big families do it and I don't mean big families like the Duggers (the older ones watch the younger ones), I mean the families that have more young kids than hands.  I think my stress level would be through the roof and that was with well behaved children.  I think I'll stick with the two I've got, I like to enjoy the attractions we go to and not worry about missing kids.  We were so busy I didn't even have time to take out my camera.
