The knife will give texture to things and make it easier for baby to grip if that makes sense.
Coconut on avocado or anything really slippery i.e. peaches nectarines etc
Its been awhile since I put any of this into practice but I remember the book mentioning the "hook method" of helping a "choking" baby but recently heard that it can further lodge the food in babies throat...so keep that in mind. Good luck!
