My little baby, my little 5 lb 10 oz at birth child, has grown so big that she can ride a two wheeler without training wheels!
At grandma's home last month, after just a few tries, decided she could do it all on her own. I almost had a heart attack for lack of protective gear but she just took off and started riding! Having a balance bike at home has helped I'm sure. We're planning on getting her a pedal bike of her own on her 5th birthday so she'll have to learn all over but I know she can do it. She's a rock star!
