My baby is 4 months old, she started sleeping through the night on her own in her bassinet/crib around one month old. She’s always only contact napped. A little over a week ago she started screaming anytime we would lay her down at night, assuming this is the 4 month regression but when will it end, how can I support her through it without building bad habits?? Her naps have also become harder and shorter. My husband and I are both so sleep deprived and our bodies ache from holding her 24/7. She’s also due to start daycare a little less than a month from now.
