Oh yeah and potato is hard to steam, when you puree it, it becomes a bit gooey in texture, so I add some water or
breast milk. You can even add formula.
With bananas, I use them fresh and just mash them with a fork. You can steam pretty much everything and freeze most fruit and veggies. Bananas are not that great to freeze. Apples and pears can also be steamed, pureed and frozen (although with pears you might get some discolouration).
