My son sings this at the top of his lungs on a daily basis. We got the deal the first time it popped up here, and he just loves the magazine. Be ready for your kids to want new trains, they love to feature those.
My 3 year old knows the tune but doesn't sing the song yet.
Unfortunately trying to teach him his 1, 2, 3s....
he has been constantly saying 1 , 2, 4, 6 for the past 6 months.....
probably because of this song.
