Ready for Spoon? 17 Month

Just give her the spoon and some finger foods and she will eat what she wants, by that age I leave my little ones to their own devices, unless dinner is soup and then I find something they can eat on thier own. Offer everything and expect her to eat very little of it, but keep offering it, it takes them uite a few tries before they will like to eat something, green beans and peas every night is ok, I think most little ones only like those for a while. But above all else don't over stress it, they will not starve and thier taste buds do grow and change.

I've been there. We found ourselves doing the same thing. As for an age, even if I could remember it I'd ignore it... every child is different and the important thing is you are offering it, so at some point she will decide she wants to do it herself. For the food options, do you have a food mill? It might open up more things you could offer her. I personally purchased a stainless steel manual one instead of the plastic battery operated ones. Slower but stronger. If it doesn't help, put some vitamin drops in her food once a day to help easy your worry. :) I personally worried and worried, and ended up sort of giving up, giving him drops, and moving on. A few months later he started eating more and using a spoon.

It takes a while before they have the dexterity to hold a spoon to get food on it and to their mouth. I think my son was 2 1/2 before I could hand him a spoon, him hold it correctly and self feed. Yogurt is a good thing as it sticks to the spoon but typically doesn't get into her mouth completely either. Let her hold it, practice and play with a spoon but don't expect too much for another year.
My son is four and can hold a fork, spoon and even use a dull knife now but it took a while and a lot of practice. A lot of mess happened until it happened! :)
You can give her scrambled eggs on her high chair tray, chicken nuggest, pizza, diced up sandwiches, Rolled up turkey with cheese slice. Try baked sweet potatoes scooped out with cheese and cooled off for self feeding. For veggies try frozen peas on her tray. Do cubed Gerber carrots, they add a little apple juice and they are yummy. I even gave my son around two a ear of corn on the cob, it was a mess but he enjoyed it. I used to typically just dice up whatever we ate as a family and put it on the highchair tray and let my daughter and my son eat with their hands.

When my first son was about 14-15 months old, I let him go at a bowl of strawberry yogurt with a spoon. He didn't spill a drop or get any on his face! He is still that way, knowing not to waste something that he loves :)
My second son is definitely not that conscientious. I took off his shirt and bib and just planned on his getting a bath after he tried the spoon the first time. I have some cute pictures of "the yogurt monster" though!
You can limit her milk so she doesn't fill up on it. After she's had a certain amount, give her water. She'll probably throw a fit or two (my kids never did like to drink plain water) but she'll get over it.
My boys loved grilled cheese sandwiches, fruit cocktail (look for no sugar added--WalMart has one of their brand), bananas, buttered whole wheat toast, quesadillas (plop a tortilla in a frying pan and put grated cheese on half, fold it over and toast both sides. Then use a pizza cutter to cut it into small bite-sized squares), canned mandarin oranges, pineapple chunks (or tidbits), diced peaches and pears, corn, brown rice, rice and refried beans, peanut butter and jelly sandwiches, frosted mini wheats, granola, raisins, grapes, diced dried apricots, and I used to flavor applesauce with pureed frozen blueberries or strawberries. Maybe your daughter would like it better flavored.
You may want to ask your daughter if she wants you to feed her, of if she'd like to feed herself. Sometimes all kids need is to feel like it's their choice, and that one of the choices makes them a big kid.
Good luck!
