Water?

Probably a really silly question,

But I drink a lot of water with cucumber in it, sometimes fruits like Berry's/oranges etc.

My son seems to love it, he likes to drink my water especially when it's has cucumbers. Is it ok he drinks it?

He refuses any fruits and veg i put down to him and have been consistently putting them down to him every day since he was 8 months. He just wont eat it.

So could I give him his own water with fruit's/cucumber in it? And is there any health benefits?
