He's superman running down the halls She's trying to put your make up on in the mirror Waiting on her best friends call I know they can drive us crazy But baby they won't stay babies forever Yeah, it won't be long One day he's gonna want my keys One day she'll be seventeen Running down the stairs in a prom dress And we'll be saying time went by fast Wishing we could get some back Cause one day they walk and I swear the next they run Baby, someday we'll be wishing for one day One day when they were young Soccer games doing homework late Her going on and on about boys at school It's just the start One day he'll buy a beer for me One day she'll have a diamond ring I'll be walking her down the aisle in a pretty dress And we'll be saying time went by fast Wishing we could get some back Cause one day they walk and I swear the next they run Baby, someday we'll be wishing for one day Just one day when they were Knocking on our door at midnight Saying, daddy, can I sleep with you After church making homemade pizza The little things that we always do Baby, time won't stop even if we want it to So we can't waste a single day... One day before we know it Our names will both have a grand before it And our granddaughter will be spinning in a Sunday dress Yeah, we'll be saying time went by fast Wishing we could get some back Cause one day they walk and I swear the next they run (I swear the next they run) Baby, someday we'll be wishing for one day So don't waste one day No, don't waste one day One day when they're young
