You just turned 5 months old yesterday yet you are already getting too big for size 9 months clothing and are currently wearing the same size diaper (4) as your 33-month-old big brother. Um, what?
A few weeks ago, you learned how to roll over from your tummy to your back. Today, you rolled over from your back to your tummy for the first time! It took you several tries and when you finally did it, you smiled and looked so proud of yourself. And then you promptly spit up all over your hands and arms. Magical!
