Purees --> "Real" Food

My partner and I could really use some good advice / encouragement here.

Our LO is 9 months old, soon to be 10 months, and at the 9-month checkup our pediatrician advised us to start to move on from purees to finger foods.

LO has done well on purees overall, which we started at 6 months, although admittedly right now we're having a "throw all spoons on the floor" phase. We've gone from single-ingredient to multiple ingredient blends using Little Spoon which has been really good. LO takes 4 x 8 oz bottles per day.

We have exposed our LO to egg (powder) before and had no allergic reaction, so a few days ago we gave our LO eggs (prepared as Solid Starts suggests, cut in a wide strip). A piece of egg broke off in the mouth, and our LO gagged and promptly threw up (formula) all over the high chair tray.

Now we are scared once again to start with finger foods given this episode. I'm worried that since we have only done purees, our LO doesn't know how to "chew" and swallow yet and we're of course terrified of choking.

We know we want to get to a place where around the 1st birthday we are doing finger foods and weaning off formula, but with the spoon-throwing and the lack of real foods so far I have no idea what a world where 3 meals and 2 snacks exists. I know at some point it will happen but it's just hard to visualize it right now.

Please please please, any/all advice on how to navigate the next few months would be greatly appreciated!!! Thank you from these first time parents.
