Litecup is a sippy cup and a nightlight!  This is such an innovative gadget and we are all impressed by it. Both my children love using it. Ms C even took her Litecup to sleep on her bed! Luckily, this is a non-spill cup which gives me peace of mind that I won’t need to change her sheet the next morning. It is spill proof but not 100% leak proof, so sometimes if you shake it vigorously, a few small drops of liquid might come out.
