I grew up with this :
So naturally...I think Mimi will love this (the homemade version) :
5 slices bread
Remove the crusts.
Cut the bread into fingers (i used cookie cutters)
Put the bread on a baking sheet and bake in a very slow oven at 125°C for 1 hour or until the bread fingers are dry and hard.
Allow to cool and store in an airtight container.
Let baby enjoy!
