Kane had grommits at 18 months babe.
And I know clefts are different, but they tend to get ear infections, and so some cleft bubbas get grommits very early, I know of some getting them at 4 months due to heaps of infections in the first few months of life...

So he's not too young, and they just may give them to him at this age. He does have to go under for it, but its very fast and simple.
