What if the mother-in-law took her grandson to her room for two months without your consent, and it was all night, or even you took the child downstairs to her room?

There may be various intentions. One is that she loves her grandson dearly, and she is afraid that you will neglect to take care of her cold or something at night, so she will watch it by herself. The second is that I am afraid of disturbing you and your husband to sleep (this is more likely if my husband sleeps with you now), and I am afraid that if you can't sleep well, he can't sleep well. I hope you can return to normal husband and wife life as soon as possible. This newborn baby sleeps at night regardless of time. It is common to wake up after eating in the middle of the night. This is a very time-consuming period. She offered to help you spend the night. This mother-in-law should be praised.
