No. Although the BLW is a new concept to me as mine are adults. However I'm a nanny and do a bit of both (as do parents) and some days are hit and miss. Maybe just a phase. I'd be inclined to leave utensils with food and let baby get on with it X
My DS did exactly this. I think he figured I could shovel in the food more quickly than he could.
I always eat with him so I carried on eating my food, feeding him a bit when it suited me. He soon got impatient and fed himself again! One of the reasons we went for BLW was so that DH and I could still eat our own meals, without having to stop and feed DS. <lazy>
He's nearly 3 now. Great eater and very proficient with cutlery.
