I buy all new dummies every 2 months (ish), the bigger size is to make them less of a choking hazard as well sp probably worth upsizing. Almost never give a bottle so can't really help on that.
How often do you ladies replace teats and/or pacifiers? I thought I read Avent suggests that you change them every 4 weeks :\: - does anyone replace them that often?
Theyre well cared for and sterilized daily. Pacifier only used to sleep and often falls out during sleep (eg, she's not sucking them 24 hours a day).
Also, how important are the age guidelines on pacifiers? If she prefers the smaller size than what is recommended for her age, am I messing up her future teeth?
