No sleep pattern.... Help 🙈

LO is 20 weeks old. I have been using an app to track his sleep for months and no 2 nights are even close to the same even well b4 the 4 month sleep regression.

He goes to sleep at the same time each night (7-8 ) and is up for the day at the same time each morning (8ish). What happens in between is a free for all. Last night he was up 7 times and that was a good night. Its 1am and hes already been up 6 times tonight and not sleeping unless on me!

It seems like every time theres a step forward there is 2 back as there is no pattern or consistency and no explaination.... I am really physically and mentally struggling 😣

Please tell me I am not alone or if anyone has any advise to offer plz do xx
