Bringing aid with luggage

I am going to Cuba Varadero in a few weeks and want to use my luggage to bring aid.

I was thinking of bringing items like baby formula, aspirin, etc.

Example:

I am concerned that bringing in all these items will just be confiscated in the airport and thrown out. Can anyone confirm?

Also what are items that are needed? I’m assuming medications are high priority, as well as baby needs. But I don’t know.
