For posts, I like 4y6m a lot. Nice and precise. I'm also fond of DSalmost5. (see below)
When speaking in real life, I'll either say "four a
half" or "almost five". It depends on the context. (I've noticed DS does this as well, but for different reasons)
For example if a random person asks me I say "four a
half". But when I am researching activities I say "almost five"
since he can be more verbal, mature etc. than the average child of 4y9m. And he is on the tall side too. In my mind he has been "almost 5" for at least 6 months now.
Asynchrony is such a hoot!
