Hi there...congrats on making such an awesome decision. I completly made from scratch all of my daughters foods. It is so much better for them, and teaches them good eating habits since you can offer them virtually every fruit and vegetable. My daughter is such a healthy little eater, compared to a lot of 2 year olds. Most of our friends who have 2 year olds also, are shocked that my daughter will eat any vegetable. I used the Cworkbook and kit. It came with the covered ice cube trays, and info for a lot of foods, how to pick the right fruits and veggies, how to cook each one, and freezing directions ( I got mine off of Amazon.com) After a while you pretty much get the hang of it and you just go on your own. I used a Magic Bullet blender for grinding up the food, nothing special. I also used a $10 microwave steamer I got from Walmart. My only must have accessory I found quite important was the covered ice cube trays. I used regular trays with saran wrap at first, but the food sucked right into it whatever smells were in your freezer. It even had that strange musty ice smell to it. The covered trays kept it much fresher looking, and tasting... especially when I got to busy to unpack and vaccum seal all the frozen cubes right away, I knew they wee fine cause I had them all covered with the lids. So that was my favorite accessorie. Also, while using Ziploc freezer bags are fine, if you will be like me where I made one big shopping trip for fruits and veggies at the beginning of the month and made all of her food (for a month) in a two day period. I found that using a vaccumm sealer kept the food fresh for months..that way I could make a bigger variety of fruits and veggies and later meals and so forth, So I'd just browse through the bags to give her a different meal each day and not the same old same old.
As for high chair or booster..go with a good high chair cause you will use it longer and it makes it easier to keep things in control as well as keep baby in a safe enviroment. I had a affordable Evenflo one but it was really unstable and scary, so I got a Chicco one that cost about $130 and my daughter still uss it till today. you can take off the tray and put it right up to the dinning table.
Well, good luck to you, it is such a rewarding thing, I actually enjoyed myself making my daughters food and knowing I controlled all ingredients. If you ever doubt yourself..make some veggies nad buy a jar of the same stuf..take one taste and you will definatly feel better about your homemade decision. Good Luck!
