Matthew is almost 6 months old, and we have just started him on solid 3 weeks ago. He was a breastfed baby for the first 4 months and he is now on formula. My doctor told me that i didn't need to give him water when he was breastfed. But since i have started him on solid, should i start giving him water? The only problem though, he doesn't like water at all. And i don't want to give him juice.
