Frozen peas are a treat for when DD eats all of her dinner
Frozen cubes of fruit puree are great for cooling porridge fast for hungry children.
My girls both love frozen bananas on a stick, dipped in yoghurt and sprinkled with wheat germ. Very nice on sore gums.
We also make iceblocks with yoghurt, mashed banana and any diced fruit we happen to have. I give them an iceblock each when I'm trying to cook dinner and I need 5 minutes of silence!
Beat softened butter, add some olive oil (about 3/4 - 1 cup oil to 250gm butter, still working on the perfect ratio!), beat some more, refrigerate in a container and you have spreadable butter that doesn't cost a bomb.
