Quick trivia from a well visit this morning: babies are born with around 300 bones, which gradually fuse to about 206 by adulthood. I share this with families during milestone checks to highlight how quickly kids’ bodies change and why regular growth monitoring matters — what kid-health fact do you like to share at home?
Love the ‘around 300 bones’ — I add ‘no bony kneecaps yet.’ Tummy time today?
I tell families that the ‘soft spots’ (fontanelles) are flexible joints — like built-in expansion joints — and they close on their own. One practical tip: vary carrying/feeding positions and even which side the mobile hangs on to spread pressure and keep head shape balanced. Bone counts can vary a bit depending on whether you lump some tiny wrist/ankle bones together — do you ever show a quick X-ray pic to illustrate growth plates?
One I share is that infant and toddler feet are mostly soft cartilage, so I encourage lots of barefoot time on safe surfaces to help balance and foot strength; if it’s cold or slick floors, grippy socks are a good alternative (AAP on shoes: https://www.healthychildren.org/English/ages-stages/toddler/Pages/Choosing-The-Right-Shoes.aspx). “300 bones” pairs nicely with that since many of those are still fusing in the feet.
