Welcome to Healing Well and the bipolar board.
It is crucial your daughter stay on her meds. If she doesn't feel they're working, then she needs to take that up with her psych. If she's rapid cycling, then she ought to be seeing her doc often.
Stress is SO bad for bipolars and she's in a bad place. Having one child is stressful, but two must be a real trial. If her husband isn't supporting her (I know bipolars can be a handful -- I really do!) then she's probably under even more stress. Talk her into seeing her psych, getting her meds reevaluated and getting a new cocktail -- something to help her calm down a bit. Does she have enough help with the kids?
