For what it’s worth, my kids hated those cups. They transitioned from bottles to these and then a whole later we went to these

But my focus was on having milk cups that didn’t have any straws so they had to tip them to drink, minimal parts to wash, and soft spouts. The first cups were a bit hard to use and my husband partially hated them because he spilled more than a few times trying to get the silicone lid on. But I thought they were easy to wash and very soft so an easy transition. The second ones were actually easier to wash than I expected, so I would recommend starting there. They are very soft nipples.
