DD will be 6 months old next weekend, and we've been giving her a straw cup to play with for about a week now (during dinner time). I usually just put an once or two of water in it (enough that the bottom of the straw is covered).
Well she surprised us at dinner last night and has apparently gotten the hang of the straw concept - which is much faster than we were assuming it would happen. I don't think she actually swallowed most of the water (since we watched it run down her chest, onto the high chair tray, etc), but she got a lot of it out of the cup.
Now that she can actually use the cup, do I need to limit the amount of water she has daily? Do you all limit your LO's fluid intake (for things other than BM/formula)? I would put BM in the cup, but watching it all run out of her mouth and go to waste would make me cry haha!
