The good news is that your beautiful baby girl is behaving normal!! As long as she's drinking and producing wet diapers she's doing as well expected for her age. She, most likely, has found more joy in her new world now that she's more mobile.....am I right? And she's found that expressing herself and trying to communicate in different ways is much more exciting than sitting in a crummy old high chair having mushy food to eat.
She will eat.....barring any other medical problems. I swear my 3 1/2 year old is making up for 2 yrs. of not eating. She did manage to eat a corner of a banana here, a crust of bread there, maybe 3 grapes after her nap and if we were having a really good day, she'd eat a bowl of angel hair pasta minus the sauce for dinner. I am not exaggerating when I tell you this. She wouldn't be the first one of my family to try out this cool diet either. For whatever reason, toddlers and preschoolers are on the go eaters.
You can try to eliminate the high chair, and just set a plate of nutritious finger foods on a chair at the table and let her go to it whenever she feels hungry. Let her see it and make it low enough for her to do it herself and if she's on milk now, leave a cup of milk with her snack. I decided after watching a few of mine go through this same thing, that it's not worth the screaming and kicking to get them to sit down formally all the time. That will come later with age, but for now I just want to get some food in her. Gradually I moved the plate from the chair to the corner of the table. Later, I would put it at her place setting but pushed back a little bit, where she knew it was there like always, but she actually had to get into her booster chair to reach into it. Once she was in the booster, she was having too much fun eating to realize that she had placed herself at the table. She was in charge....exactly what they want!! The sweet thing, is that I wasn't the bad guy for getting her there.
Now, she knows where the food is and if I'm good at timing it......it falls right at mealtime when everyone else is sitting down so it's just part of the normal routine.
I hope this has helped. Just make sure at night when she's sleeping....you precut and prepare all her favorites for the next day, so you will be ahead of her.
Happy eating!!
