I think my wife is too obsessed with hygiene and is overprotective of our daughter. How do I tell her to be more carefree?

It is important for babies to have a clean environment. Keeping both the baby and bottles clean is of utmost importance. Better to have a clean home and healthy baby, right? However, if your wife is insistent on wiping every single speck of dust off and you notice that she's cleaning the house every single second, then it does seem a bit overboard and may be a sign of OCD. http://www.kir.org/babycontent/hygiene-and-sterilization.htm
