Hey glow Mommas! So all my pump instructions and Hakkaa instructions say to sanitize all of the stuff every time... but a dhoula friend of mine said she uses the hakkaa throughout the day and just washes with hot water and soap and then sanitizes at the end of each day.... do I really need to sanitize EACH use? I read an article online too that said some people wash with hot water and soap. What’s best? I go through these Medela sanitizing bags like toilet paper....
