I would suggest to read or Watch videos about regulating emotions and nervous system. It takes time but with practice you will be able to reduce emotional blow outs and regulate and self soothe.
I am sorry you are going through this and it's important that you acknowledge what is happening. I would get an appointment with the GP for both to check him and to discuss about your well-being. Also is baby sleeping during the day? When my baby was waking up so often she had a cold or was teething or was overtired. Good luck
I know it’s very difficult, but don’t worry this too shall pass! My son started sleeping through just after his first birthday. The winter period is difficult, is little one cold ? How is he eating for you throughout the day, is he hungry? Teething? Unwell? Honestly I co slept through the winter last year he was 10 months and that improved his sleep drastically. 8/9 wakes for a 9 month old is a lot, that’s usually more common with newborns.
