I have decided to start potty training my 18 month old daughter soon using the N75 method. I feel pretty prepared but my question is around sleeping. She currently sleeps in a crib and I don't know if it is too soon to transition her crib to a toddler bed. I know it will take a while for her body to adjust to holding it all night so I do expect to have to change the sheets for a while in the middle of the night. Do you advise transitioning the bed before we work on training so that she can eventually get up in the night to use the potty herself? Thanks in advance!
