Babies don't keep!

Time feels like it's flying and it's overwhelming. I seriously feel distressed over it. We didn't buy a ton of clothes for my baby but she is growing so fast that she doesn't even have time to wear all of them! She's changing and doing new things every single day and I feel like I can't blink or I'll miss it.

How does everyone deal with their babies growing up so fast?? I really don't want to feel sad about this but I'm having a hard time with it.
