My kids are 4, so the memory is a little hazy, BUT:

FEEDING: We used the Chicco hook-on chairs. They take up way less space than high chairs. No help with the food, sorry.

TRANSPORT: we used the Valco runabout. It is a double jogger with a booster seat. It fits through doorways, which was key for me, and is so easy to push. It is pricey. Everything we had was hand-me-down, but we did pay full-price for this. It was worth it for the freedom!

PACIS: They are a pain. My dr. said not to worry too much about them until they start really talking, so they don't impede their speech. Two of mine just gave theirs up at about 10 months. The other was a challenge. Finally got rid of it around age 2.

Good luck!
