Do you have to bathe ur baby after every feeding also or do i need to do something different?

She sits in her highchait, but i cant put the tray on top cuz its too high on her, and i tried using bibs but she adamently rips it off every time lol and she puts her fingers and hand in her mouth in between bites. I have tried to just wipe her down but she feels sticky so i just rinse her off in the tub but i am doing this EVERY time and wondering if there is anything I can do differently to avoid 3 rinse off baths of WATER, no soap, just water, a day....baby handcuffs? LOL
