My Daughter , 8 Years Old , When She Swims

My daughter , 8 years old , when she swims in the pool and the water gets into her nose , her nose is so irritated that she feels it immediate pain. This is usually is followed by congested nose .
I use Vaseline to cover the inside iPod her nose but the cream is easily removed by water .
During the training , she has to stop several times to put the cream again . What to do?
