Get a grip!

Kelsey Grammer had a tighter hold on his Starbucks cup than his daughter Faith when he arrived in LA yesterday from New York.

His wife, Kayte, also seemed in need of a parenting lesson minutes later, jumping with the 4-month-old tot into a car without a child-safety seat.

Grammer, whose Starz show “Boss” was recently canceled, later told TMZ through a rep that they put Faith in a child seat before leaving the airport grounds.
