Rompers and Babygros

It feels like Oli is growing way too fast.  I look at photos of him from a month ago and I can see noticeably how he has grown and I feel like these baby moments are slipping threw my fingers and there is nothing I can do to freeze the moment.

To me baby clothing means rompers and babygros.

So when I buy clothing for Oliver, I want to buy rompers and babygros.  And that was fine when I needed to buy new born and 0-3 month clothing.  But 3-6 months a whole different kettle of fish, it seems like the shops want to force me to buy shorts and t-shirts.  Cute shorts and t-shirts for that matter and when Logan was little I found them very appealing.  But with Oliver, I want to hold on to the baby moments for as long as I possibly can!  I mean really he is going to be wearing shorts and t-shirts for the rest of his life, why start now?

Am I possibly going crazy and holding on because I know this may well be my last baby or is there a limit on the number of cute and pretty rompers out there for babies?
