What to put in First Aid Kit

Miranda • Wife and mommy to a little boy and a little girl💓

So I’ve decided I wanted to make my own First Aid Kit that I could keep in my daughters diaper bag for emergencies, because you never really know what could happen. I have a 2 year old and she’s not born yet. What would you recommend to put in it? Of course the basics like bandaids and ointment and hydrogen peroxide. But what else should I put ? For a toddler ?
