How to train my 9 months old to drink from a cup? Or is it too early to train ?

There are no spill cups available if you’re worried about spillage.. but they require quite a strong suck. My first child hd trouble with every kind of sippy cup available, regardless of the kind of spout. So she stuck to straw bottles/cups initially, then later on after 18 months, we trajned her straight with a normal cup
