Sleep issues

For the past almost 2 months my son’s sleep has gotten really bad. He wakes up every two hours sometimes every hour and I feel like I’m going crazy with no sleep. He’s 16 months and I think he’s teething but who teethes for almost 2 months? I’ve talked to his doctor and she said she does not think there is anything medically wrong with him. So idk ? Anyone else going through something similar. Also he keeps rubbing his face and he is biting me (which is usually a sign he’s teething) Give me some hope and tell me I will sleep again soon 😭
