I've taken my LO in a pool twice. Since its summer I took him yesterday to the lake and today to the creek. Both were pretty cold, but it was 90+ outside. He cried at first and then loved it and didn't want to get out. I took him out when I noticed his bottom lip quivering. I had him sit in the sun for a minute and didn't put him back in. FTM, so I need to know everything about babies and swimming in creeks and lakes please!
