Hey mamas. So my 13mo still is waking multiple times (2-3) at night, I'm six months pregnant, and hubs is completely exhausted from taking on the bulk of the night wakings. I'm ready to sleep train her, but I'm not sure if I should take a different approach since she's older?

I sleep trained my first at 8mo because she dropped the last night feeding on her own then, but my second only very recently dropped that feed. I did a version of Ferber with my first, is that ok to use on an older baby?
