New Backpack

We've been looking and looking for a little backpack for Jack to carry his pump in. The one that came with the pump would be big for an 8 year old so there was no way it would fit my tiny boy. We bought a bag at pottery barn that was designed to be hung over a chair to collect Christmas cards but he outgrew it in about 3 weeks. We finally found one made by Samsonite and ordered it online. It came on Friday and it is so stinkin cute!!! Yesterday we went to the fabric store to buy the supplies to adapt it with a chest strap. We put it on him this afternoon and he, as we expected, got very upset. We kept it on him for about 15 minutes and after about 5 we got him distracted and then he tolerated it. About halfway through we put the pump in the bag. He was a little off balance at first but he got the hang of it. We had to take it off when he started to crawl away though because the backpack slides over to one side and it pulls him over!
