Sippy cups?

Ch

This might be a silly question but is anyone else still using sippy cups or have you transitioned to regular cups yet? Our pediatrician has encouraged it since about 12 mons & our daughter knows how to use one but the problem is when she decides shes done she gets milk everywhere. Sippy cups are so much more convenient such as on trips and in car rides etc. just curious what everyone else is doing so far...?
