We've done jars and made my own, Stan's not picky though will eat most anything
we do fruit jars. they're yummy.
Usually with Alasdair there are no left overs however with the fruit jars I usually scoop out everything into a bowl and then put the empty jar back in the fridge. The next day I put Ally's whole milk in it and shake it up and then use the milk to make his porridge
