My nephew is 3 1/2 and is JUST getting potty trained. he's my sis's bio child and when she asked her doctor about it, she was told that boys are later than girls and some boys need more time than others to "get" it. L wears underwear 'most' of the time but still uses a pull-up sometimes and every night for bedtime. her pediatricain told her its oompletely normal
