Ah! I can understand what you must be going through. Your heart sinks whenever you think of leaving the baby, and no matter, that be your husband or parents. But, I think, do not worry. Your mom is his 'two times a mom', and she is going to take care of him with more love than probably did your time. I know it would be difficult initially, but when it is your mom then I think you should let all your worries rest. Go ahead and all the best.
