A fairy doesn't cast a spell that imparts sufficient neck strength for them to safely face forward on the eve of their first birthday.
New rule is age 2, not age 1, just for anyone reading along who may not know and has kids of this age (probably doesn't apply,. but just in case).
Anyway, I've always assumed that when they make guidelines like this, they're going by a 90% rule, or something...90% of kids have sufficient neck strength by age 2, or whatever. Many will have it before and a few will not have it till afterwards. Of course it doesn't magically happen on the eve of the first birthday, but.
