Let us ignore the big red flag of someone having kids by multiple partners in rapid succession. I'm down with the family bed up to a certain age (thru the single digits), and depending on circumstance (illness, trauma), at older ages with a same-sex parent. So if the last divorce is recent, I don't see a big issue. But, and this is a big one, the "family bed" is totally inappropriate for a non-bio parent past toddlerhood. It sets up an enormously conflicted, inappropriate intimacy for the child. If you are in a new relationship... . the family bed has to stop (unless we're talking babies). Seems like the 8yo was ready and at the right developmental point to sleep alone, and that all happened in a healthy manner. Four is still gonna wanna sleep with mom, and it may be developmentally appropriate for this child. If Mom's gong to be in a new sexual relationship (
), then she needs to work on getting 4yo into a new routine. Won't be easy and it will take time, that's just the age and the circumstance. All that aside, she may be co-sleeping for her own comfort as well (mom I mean). That's pretty common for single moms, whether they are BPD or not. Not necessarily healthy, but not necessarily UN-healthy. With 2 girls at young ages... . only an issue upon a new sexual relationship. If 1 kid were a boy, or if the kids were over age 10... . then obviously a problem regardless of new relationships.
IMHO
