is this wrong....?

For as long as I can remember, The Boy has always been interested in whatever it is that I am drinking. If I have a glass of water, he needs to have it. If I have a soda, he needs to have it. If I have a coffee, he needs to have it. It's not that I don't want to share (well, it's kinda that I don't want to share), but it's The Boy who really doesn't want to share. He wants to take my drink and make it his own. I'd be happy to give him a sip of this or that if that's where it would end, but that's not where it ends. It ends with me in utter frustration, wondering why I can't do anything without being harrassed. I mean, I just want a drink of water for goodness sake!

The result of this has been that I simply avoid drinking things around The Boy. I don't think I thought the issue through and came to that solution... but over time, that's what I've noticed is happening. I just don't drink around The Boy. Since I am around The Boy pretty much all day, what that means is that I hardly drink anything. As a survivor of 12 (count them, twelve) kidney stones, not drinking anything all day is not a very appealing option for me (besides the fact that not drinking anything all day is probably not a very appealing option to anyone).

Out of sheer desperation recently, I simply poured part of my drink into a small cup and gave that to The Boy. OMG, it worked! He walks away with his own cup and is happy with that. I am relieved. The result of that, however, is that now The Boy simply asks me for his own cup of whatever, whether I am drinking it currently or not. Today it was tea. So, I made The Boy a cup of tea. I used decaf. Just plain decaf Lipton tea. It felt so odd the whole time I was making it. Serving tea to my 2 year old just seemed unusual.

My question is this: Is it wrong? Is there any reason why I shouldn't be serving The Boy tea? I mean, besides the fact that he's a bit young to learn how to hold his pinky finger out as he sips?
