We have a 4 week old baby with reflux, she was doing sort of okay with bedsharing for about a week, but it's getting to be where she wants ONLY to sleep sitting up in my lap. Honestly, I can't sleep like this, so not sure what to do. Going 2 days on without sleep then one good night of sleep then 2 more days without sleep is a hard and pretty unhealthy pattern for me.   Obviously I won't just let her cry, but how can I make her sleep again in some possible way I can...
