2 mo suddenly clingy

Becca

My 2 month old (9w) is suddenly so clingy, she used to take 2 naps a day in her crib for 30min to an hour but now she just cries. My heart can only take 10 minutes before I go in and get her, and then she immediately sleeps on me. I try to out her down a couple times and it just repeats. She got her shots on Friday but seems to be clear of anything that was. Hugging her over the weekend. We had a really hard time putting her down last night as well, which usually she goes down easy. Could this be shot related? Or is there a 2 month sleep regression I’m not aware of lol! I just want to get some things done around the house but can’t seem to get a second to put her down
