OP sorry to hear you had a fight have you spoken since? your only looking ourt for the best interests of all involved.
id be very unhappy with your friends if i were you too! how rude of them

as for DD and big bed, get two bed rails, one larger and one smaller so it goes down the length of the bed so she cant get out! thats what we did for S when she went into a bed, though she was older at 2 yrs.

im giving up on sleep too!
