Baby unsettled at night

La

My little girl is 13 weeks & usually sleeps from 7-7 with one feed around 3 but for the past week she is really unsettled at night & tosses & turns a lot for her dummy. Every 2 hours. She Wants 2 feeds again at 1 & 4! Could this be a growth spurt or teething? She is showing the signs for teething. I am like a walking zombie 😫😂
