Problem with nap time ! Help

My daughter will be 4 months on the 17th. In the beginning I would be able to put her down for a Nap. The last month she will only nap on me. When I try and put her in her bed she wakes up screaming instantly. Any advice on how to get her to nap in her bed? She sleeps in it fine at night
