I agree with everyone else but it is important that you talk to your DS1 about how taking other peoples tablets can make you very sick (which is not good) and that it is better to be strong and healthy than sick.

I am jsut worried that one day he will pick up some medication and consume it and end up very sick.

I would try and make a big deal about how great it is that he is so healthy and strong and is always there to help mum IYKNWIM.

I agree with you that he is most likely doing it to get you attention so make sure you give him your attention for being so strong and like a super hero!

Good Luck
