My 10 month old is OBSESSED with all things cup/bottle/drinking related. As a result of this, he has ended up having sips of our drinks when we have squash. He is now desperate to drink squash and will spend an entire mealtime shouting at us an pointing at our glasses, rather than actually eating his dinner.
This evening I poured a very small amount of squash into a (normal child size) cup and diluted it a bit more so it was very weak. He drank it all up and then cracked on with his dinner. Seems like a sensible enough solution to me but I don’t want him to start refusing water! Currently he will happily drink gallons of water if you let him so not really an issue.
