Vacation/Flying

We will be going on out first vacation with our LO in three weeks (he will be 6.5 months) . I am in need of some advice and recommendations.

1. We will be spending a lot of time in the pool and ocean. What are the best safe/natural wipes to clean off my breasts before nursing my LO? (I know it won’t be realistic to expect to have somewhere I can wash off everywhere we go).

2. Best all natural/safe sunscreen for baby.

3. Best swimming diapers for baby that won’t leak out runny breastfed baby poop lol

4. We did not get him his own seat so we will be holding him on our lap. How does checking car seats work? Do you buy a special cover for it and that’s it or???

5. Should I opt to for a Pat down of me and my baby instead of the machine they use?

6. Best compact tent to have at beach.

7. Best floating device for baby.

8. Any other advice??

Thank you!
