Yes, maintaining consistency amidst the distractions of daily life is certainly a challenge! Emphasizing the importance of keeping up the good work, especially when visiting family or friends, helped my children stay on track. We also made sure to have multiple pairs of training pants handy and packed our special potty seat for outings, which provided some familiarity.
I remember having to be extra vigilant and proactive about prompting my child to go when we were out - a timely whisper of the special code word helped remind him to go when the opportunity arose! For shy types, it could also help to have a private, familiar space to retreat to - even a curtain or two hung up in a corner worked for us when visiting noisy, crowded relatives!
Did any mummies find a particular method or trick helpful for keeping toddlers on track outside of their comfort zones?
