People with 2 or more kids of only one gender save a year on clothes.
My ds2 wears all of ds1's old clothes (happily, mind you. Heck they look fine and are "new" to him).
Ds1 just outgrew a pair of pajamas that he tried on - I said Ok - hold on - let me go put it in ds2's drawer! LOL!
Seriously - we buy ds1's stuff ahead of time, typically on clearance or on great sale - and then reuse it ALL with ds2!
We would have a very different situation if ds2 had been a dd! LOL!
