medical items to have in house

I registered for this but didn't get it at my shower:



It contains:

teething pain relief gel
saline drops
moisturizing nose gel
decongestant nose drops
multi-symptom cold formula
gal relief drops

I know the gas relief drops are a MUST have but what else do I really need to have on hand? I guess its better to be prepared with this sorta stuff then a middle of the night run out to a drug store.

Can experienced moms give some advice on what is a MUST have in the house? Please include the 'diaper' things to have too, like diaper rash creams/ointments/etc.

THANKS SO MUCH!

Honestly I didnt have much at least that I remember.
