How do you deal with a kid who suddenly hates showers and has started faking them?

My 10 year old son has recently started to hate taking showers. We make him shower everyday and it's always a battle. He plays sports and spends a lot of time outside so he really needs the shower. We also want to get him into the habit before puberty so he has hygiene handled before that comes. My oldest (son) didn't start puberty until 13 but my daughter started at 11 so we don't know when he'll start. Better safe than sorry though.Every night we have a battle about the shower. He complains that he doesn't need one and after much back and forth he eventually gets in. Or so we though. He has apparently been running the water for a few minutes and jumping in for the last minute or so just to wet himself and his hair. He doesn't have body odor yet but we noticed he didn't smell like soap or shampoo or conditioner and he eventually confessed. He also gels his hair in the morning and we noticed the gel was still in his hair at night.I'm not really sure what to do. Do we just do a smell test every night? Is this just a phase? Neither of my older two ever went through this. Is there a way to make the shower experience less terrible before puberty takes care of that naturally? via /r/Parenting https://ift.tt/2PuiRoM
