Unfortunately, Aiden didn't enjoy the beach much. It was crazy windy, so our sun cover tent kept trying to blow away. We ended up putting the back half on the ground so we had a makeshift cabana. Every time the tent would blow back a little and expose Aiden to the sun, he would scream. Then after I put sunscreen on Aiden he rubbed his eyes. He started screaming 15 seconds later, which confirmed that sunscreen had gotten in his eyes.
He was cranky for the next couple of hours, all except for when he was playing in the water and in the sand. Well, until he rubbed his eyes with sand on his hands, of course. UGH. We'll have to try the beach again later. I would imagine the best time would be once Aiden can walk, so he doesn't have his hands in the sand the whole time.
