P.O.
Baby sit for her, listen to her vent, help her with dinner/chores, help her financially, pray for her husband to feel contentment and satisfaction in his jobs. Since he starts and quits so often, he might be the type that enjoys variety versus the same job over and over. In that case, he could do contracting instead where it would not be considered hire and fire. If her husband is an engineer, quite likely he is not the social type and even though it might seem he cannot do a good job as care giver, I believe he will do a good job HIS way if placed in a position to do so. If she is so concerned, then put the 2 yr old in daycare. The other two are old enough to stay with their dad.
