4 month leap?

Samantha • 👧🏻🤰❤

My daughter is almost 17 weeks. The last 4 days its been hell trying to get her to sleep! We've spent hours each night shushing, rocking, feeding... shes also teething. We give her tylenol at night just incase to help with any pain. She normally is easy peasy to get down and sleeps about 11 hrs straight. But now she will wake up (and usually only once) but be up for hours. Is this the dreaded 4mo regression? Is it just teething? Im at a loss.
