My DH does this to me all the time when we are going to the mall, zoo, etc. and he doesn't want to be bothered with the stroller. It always backfires on me because my 3 year old ends up crying that she wants me to carry her rather than DH. So I end up doing at least 50% of the carrying. Also, will your 5 or 6 year old want to be carried once they realize their younger sibling is being carried everywhere -- I know that my 5 year old would, LOL.
