HELP!

Dana • Happily married and with 2 beautiful babies 💑+🙇🏼💙+👶🏼💕
Ladies, it's been a long time since I've posted in this group. I'm really desperate. Looking for advice. My son, Adam, is now 13+ months old. He already has 21 teeth, getting #22 now. When he's teething he wakes up a lot at night but lately he's been waking up frequently and screaming/crying. Sometimes abottle  helps him return to sleep for atleast 3 hours or so, other timesnothing  helps. My husband and I are exhausted! And we have been on edge, especially me with my heavy periods and depression, so we've been arguing/yelling a lot more at each other and my son will scream and cry then also. We are not violent but sometimes loud and we kiss and make up in front of him and he smiles and responds. Basically, I don't know what's going on with my boy? If it's teething or if it's us who are causing these wake ups and crying/screaming? He does it sometimes when he's really sleepy as well.  I'm feeling really guilty and like an awful parent, especially since occassionally I lose my cool and just can't deal with him when I'm so tired and he's crying. Any advice or feedback?
