Most pools you go to will have a separate baby area. I would suggest letting her play in that area, it can be really fun for her! She would love to go down the slides and use buckets, cups, shovels, etc. to play and explore. Just playing in the water will help facilitate a lifetime of wanting to swim, etc. You can also take her in the big pool with you of course, like you mentioned, at that is also fun, but just be sure to mix it up. I find the main pools are less busy during the late afternoon/early evening. You can easily go there and not feel like your little one is being overwhelemd. We live in OP and are happy with all the pools around us. Tomahawk on about 119th and Antioch also has a sand play area in the baby pool and it's really fun!
