We live 5 minutes from the beach so have spent a lot of time there with the kids when they were little.
Is your 10 month old mobile? I would suggest making sure that you have a large blanket, large enough that your baby can still have some mobility and yet not always be right next to the edge of the blanket. That is, unless your baby is fully mobile in which case, watch out!! :lol: Also, if you are going to be somewhere hot, have a beach umbrella along too unless there are a lot of trees where you can sit in the shade. Also, sunscreen is a must and a good sunhat of course. Beware that sand sticks to sunscreen and is really yucky and gritty to clean up but of course sunscreen is worth it!
Our kids have ingested a lot of sand in their lives :oops: , it just comes back out the other end but just make sure you're not where there's any animal or bird poop around, that can be a real problem at a lot of beaches and you need to watch out for that.
That's all I can think of, but it's a bit different for us as we live so close to the beach if we forget something we can always go back home and grab whatever.
Have fun!!!!
