Clingy 4 week old

Has anyone else experienced this? My daughter is 4 weeks 3 days, who would normally settle in her cot during the day/night for the past couple of nights just wants to sleep on me or my husband i don’t like the idea of her sleeping on my chest as she makes me sleepy! I don’t know if she’s having a growth spurt or not, my mom is being very opinionated and telling me to let her cry which I am doing to a certain extent but not for long any tips please?!
