We found this backpack to be an excellent way of transitioning our son out of the diaper bag.  With a 2nd child due our goal was to clear space out of the diaper bag in order to make room for all the things that are necessary for a newborn.  Our son was about 2 years old and we were able to move a couple spare diapers/wipes, book or two, small toy, snack and sippy cup over to this bag.  The best part of all was convincing him to carry it.  Most times we don't need it but for those times you do it is nice to be able to let your own child carry his own weight.  Now if I could just put him to work.

The actual build quality of the bag seems to be very good and has thus far remained looking very clean.  It gets used every week and carried/dragged by our 2 yr old son and has held up to the abuse nicely.  It's been a great purchase and one I'm sure we'll try again when our daughter is a bit older and able to pick out her own favorite animal.
