It's getting to the stage now where DD wants her DB to sleepover. I'm ok with this relationship and verging on comfortable having him over to sleep but I have younger children and am worried about setting a precedent. I think DC are quite black and white and would see me letting DD1's BF of 7 months sleeping over meaning that their partners of 7 months will be allowed to sleepover. I'd rather judge each relationship by its own merits. How do other MNers deal with this, please?
