Could it be? My baby is three months old already? She's already grown out of her newborn diapers, and the size ones... and now she's in size twos. Seriously... Make time slow down!
This girl weighs 14 pounds, and my arms can feel the difference when I carry her carseat. She doesn't fit in her baby bathtub anymore, and my back feels the difference when I'm leaning over the regular-size tub. Her newborn nightgowns are already in rubbermaid storage bins and moving into the garage. Time is going by too fast, and there are still clothes with tags on them that she's never had the chance to wear. Thankfully my sister-in-law is pregnant (woohoo!) and I'll be able to pass some things on.
Basically, I'm just trying to keep up. Savor the moments. Capture them on film, if possible. I tell myself to enjoy each stage as it quickly comes and too quickly passes. And I say "Thank You, God!!!" prayers every chance I get.
