Has this happen to anyone?

My LO is 4 months I’ve never replaced her pacifiers😞 I’ve always just sterilize them weekly but I just found out I’m supposed to replace them every two months. 😕I’m feeling some type of way🥺 there’s so much I still don’t know & idk if I’m doing anything wrong or not she’s my first. I do replace her bottle nipples, replace her bottle brushes. I’m now doubting myself & thinking I might not be doing other things right.

Edit: Thank you so much ladies you guys have made me feel a lot better 💕
