Extra Clingy Baby

My daughter just turned 10 months old and had been mostly doing fine with going to bed in her crib after I nurse her. Bedtime has never really been a problem with her. But the past few days, she just will not calm down for bedtime and gets so upset when I put her in her crib. The only way I got her to fall asleep tonight was to lay down with her. She’s been waking up about every 2 hours at night too. She’s been wanting to nurse for longer periods of time, as well, and gets to a point where she’s basically using me as a pacifier (she won’t take an actual one). She could be cutting another tooth but I’m not sure, and she just took her first steps on her own today, so that’s a lot going on for her. Any tips and/or other ideas of what this could be? This mama is exhausted.
