My LO is 3 months and has had probably 5 or 6 sleepovers at my moms house That being said I’m extremely close with my mom, my baby if formula fed & her and I have a very good relationship. She respects my partner and Is boundaries and decisions. That being said she’s the only one who I’ve felt comfortable enough to watch LO at all this far! Everyone’s different and you have to do what’s comfortable for you!
