I have 2 boys that are 3 years apart. I started saving clothes for DS2 before he was even born. Both boys have a different build and DS2 is quite a bit bigger than DS1 was at this age. He seems to grow out of sizes faster so it's been nice not having to run out and buy clothes all the time. I know that here before to long I won't be able to pass down everything. DS2 will probably never wear slims like DS1 does.
