First aid kits

As baby's getting bigger we came to relize we are lacking in the first aid area. The ones that come prepacked are exspensive, so we're making our own. For the car and for our home. What are some ideas for kits that you have or just suggestions. We have band-aids (duh.. Lol) neosporin, bug bite cream, gauze pads, paper tape, motrin( for adults), infant Motrin. I just need to buy those instant ice packs but I'm just running out of ideas. Any suggestions would be appreciated. 😄 thanks in advanced👶🏽💁🏼
