What would you do?

I am a single mum with a 11 month old baby. I am in my 4th year of residency. My mum helps a lot with the baby, she’s a retired doctor. But now she has to go back to our hometown, while I need to stay here to finish. So I have 2 options- Option 1-Keep the baby with me, most time in daycare and juggle extreme workload alone. Not good for my profession or for the baby, but we will be together. Option 2- send the baby with my mother where she will take her of him 24/7, he will get the best of care. But he will be away from me. Logically he should go with my mum and I will see him after 6 months. Emotionally, I want to die at the thought of him leaving. What would you do? Think for a moment and answer.
