Ideally, you want your child to try using the
potty training underwear for naps on the big day; however, if you are concerned about her sensitive skin, I would suggest a pull - up - but in a different brand - because she is all grown up and now only wears underwear - and then the pull up goes on just
before nap and comes off right after the nap - most of us urinate within a few minutes of waking up and you don't want to give her the
opportunity to go in the pull up because it causes confusion - so try to remove it
before she urinates and try and have her urinate in the
potty.
The first
opportunity you get to sit down and rest your tired pregnant self is the second your toddler must have milk / water / snack /
potty immediately, despite being perfectly fine a minute
before
