If I get out of the pool, I bring him with me and 3.5 yo has to sit on the stairs and wait for me. 3.5 yo wears his floatie, and turns out he is very apprehensive about his face going in the water so he is happy to stay in the shallow end or near the stairs. Pool is small enough that I could reach the other side in about 5 seconds if needed.
I am glad it's been working out, OP. I have twins, and I am finally comfortable taking them by myself. They are 2.5 and there is a toddler pool where we go.
