I write this with so much pride for my four year old: Reid rode a bike for the first time! I am beyond amazed that with very little assistance and skipping training wheels, he was able to ride a bike on his first try.  All I have to say is: balance bikes are amazing!We gave Reid a balance bike when he was 2.5 years old.  He took to it pretty immediately and loved going on bike rides around the neighborhood.  At first he simply walked with the bike (probably for the first 6 months) and then around 3 he got the hang of it and would balance and glide along…
