Baby does not want to sleep alone.

Hello Mama's, My little one is currently 2 months. I'm looking after her by myself in the day and I need a little advice on how to let the baby sleep on her own for daytime naps. Each time I set her down she will cry out. She only wants to sleep when she's carried. I understand that she feels safer sleeping on me but she's getting a little heavy for me. Swaddling, the traditional baby swing and the rocking crib doesn't work. Does anyone have any advice please?
