I understand your fear but the studies show that adult-baby sleepsharing fatalities are NOT caused by an unimpaired breastfeeding mom overlying on baby while sleeping on a bed. Sleep research has shown that breastfeeding mothers tend to be very aware of baby while they sleep, and if baby is at the breast he is typically going to be far away from pillows that might obstruct his airway. The risks (ands there are risks) primarily have to do with other factors. Here is some info to start with so you can research this for yourself if you like: https://www.llli.org/faq/cosleep.html
I think moms who want to bedshare generally become more comfortable with bed sharing as baby gets older and bigger.
Ugh, moving. YES get help all the help you can get!
