What size diaper is your baby in?

Brenda • 🦋🌹🌈🌪🍔🍭🍼🎀🧸🎉
My little Annabelle was born on February 22nd. So she's just over 4 months old & as of yesterday, she weighed 16.1lbs & I just moved her up to a size 4 diaper. (I realize the weight size is 22lbs for a size 4, but I always like em a tad bit bigger as it holds the messes better.) 
So I'm just curious.. 
How old is your bundle of joy?
How much does the little pumpkin weigh? 
& what size diaper does your sweetie wear?  
Thanks I'm advance!!😃
