- hi everyone we started potty training 1.5 she does everything perfect as far as going when she needs to go flushing and saying i peed or poop . But this is only done when she isn’t wearing any bottoms . We try to put panties or pull ups on and she goes in them :( i try to show her how to pull them up and down but i noticed that’s where she struggles ... she can’t get them down properly in time or she has trouble pulling them up in the back ... idk what to do help !! 😫😭 she’s so close sigh*
