Milk out of what type of cup 1 year olds

What is your bubba drinking milk out of now? (Other than breast)

Open Cup

360 cup

Bottle

Straw cup

Sippy cup

Etc

Any pictures would be great

My little girl is 1, was breastfeeding exclusively and started bottles of formula a few weeks back but thought maybe I should switch the bottles to a cup before she becomes attached

Still breastfeeding at night bottles in the day

We use MAM bottles And a 360 cup and a straw cup for water
