Leaving 1mth baby with inlaws

Hello Mummies, I'm a first time mom. and its just been 1 month plus since i gave birth to a cute baby boy.. Unfortunately due to financial reasons I had start working soon after as to assist my husband financially. And on top of that i'm taking a part time diploma which starts after work. Hence, we place my LO with his grandparents. Here's the thing. me and my inlaws stay far apart so at most of the weekdays we will let my LO sleepover at their place. but i realised that whenever we bring him back during the weekends he will start crying really badly that im so scared that he might get seizures. And as a mother i feel devastated, my in laws said he rarely cries when he is at their place. So i'm guessing that he isnt comfortable at his own home and prefers to be there. Which made me feel sad and distant from my LO. i cry at night when he isnt around. i just dont know what to do. what if he grows to not love me.. all the thoughts starts to pop in my mind. I'm scared that this might lead to depression. i dont know what to do. am i a bad mother? has anyone else left their 1 month old child to start working? is working this early a good idea?#advicepls #1stimemom #firstbaby
