Hi Kirsten!
Finger food is grand. The expressions on their faces as they cram this yummy stuff (or yucky stuff) in. Great for their finger control/dexterity!
We just mix it up with my dd 13mths.
There are some things that really work better on the spoon - give her the spoon and see if that will help her take it. Try some sticky things first, things that don't slide off too quickly while they are waving it around - thick yoghurt, rice pudding, thick casseroles...
And give a variety of finger foods - I also find that while dd is preoccupied in picking stuff up off of the tray, that you can spoon stuff into her mouth...
You introduce a spoon and fork at any time - it just depends on how tolerant you are of mess! My dh couldn't stand watching the smearing over the face and hands, and then when stuff dropped she would play with it...I thought it was funny and a learning curve. How else is she to learn?
Hope this helps.
