she drinks out of those tommee tippee easiflow cups (the ones with the removeable spouts) anyway i got 2 of them which i rotate. Now i feel like the crappest mother coz today i removed a lid to put in fresh water and noticed black around the inside of the spout, i removed it and looked inside and it was disgusting all black and horrid. I always wash the cups well and the outside of the spout but i never take it off, i wash the lid well and the outside of the spout too. I feel terrible that i've been letting her drink from this cup
