My First Tervis sippy cup.

My toddler and I received the Tervis sippy cup in the mail to try out from Influenster.  When we took the Tervis cup out of the box for the first time we were excited because the design on the cup is my little ones nick name Monkeys!  The cup is clear but insulated to keep cold things cold! I must say I really liked this for the times when my little one drinks her milk slowly or is on her second cup. What  I did not like is that you really have to suck hard to get the liquid out of the cup, this is great for keeping the liquid from spilling out of the cup but she kept getting frustrated when she would try to drink out of the cup.  We still use this cup just with out the no spill guard.  Over all I think that we would be likely to recommend this cup with the little note that it takes some practice and some hard suction.
