I'm wanting to take Abby swimming at our apartment's pool. I got the swimsuit and a little boat with a cover over it. Now the problem. I was looking at the lil swimmers and the small says 16lbs and up. Ok, Abby is 5 mths. old, but she only weighs 12lbs. I need to know from ya'll if the swimmers are gonna be to big or what ya'll use. Please help cause I have no idea!!!!!!!
