I’m wondering how old is too old to start potty training? My LO is 18 months old and I’m so proud of her, she just pooped and peed in her potty😃😃 But I know she won’t be able to control her body or tell us when she has to go until she’s older. Just wondering if starting now, might get her out of diapers sooner🧐
