Hi S., I have a three month old and we went to the pool for the first time yesterday. I bought Banana Boat Baby Tear Free and it is SPF 50. I found it at Wal-Mart for about $6.50. It worked wonderfully and it even got in her eyes a little bit but didn't bother her at all. Let it sit at least 15 minutes before going in the water. Good luck!
