Size 3 - The upside?

As I mentioned earlier on Friday, potty training is a very slow process with Abby.  S-L-O-W.  So, meanwhile she is wearing size 3 diapers (and periodically some Pull-Ups).

On the other hand, we are squeezing Marilyn's chubby & chunky tush into the last of the size 2 diapers.  When I go to the store this week, I will be upgrading to the next size.  That would be size 3 diapers.

So... is this the upside to one daughter not being potty trained yet and the younger one growing like a weed?  They will both be in size 3 diapers starting tomorrow.  Not sure if this will save us money or not, but it sure will be more convenient.  Wow.  Didn't see this one coming.
