FIrst of all congratulations!
Secondly - you are definately not alone! Many babies go through a "witching" hour - although for many bubs its more like a few hours! My Izzy is only just starting to get a bit better but its taken alot of time and distraction. I really feel that during this time they want attention and comfort so I would just do whatever works. If he wants a dummy give it, if he wants a feed give it, I agree with the aba here - they wont take it if they dont want it. Izzy would feed much more frequently during this time. Maybe try bathing during this time if he likes it, sling wearing and lots of cuddles! I aslo used to go for a walk with the pram every day during this time to get her to sleep - as of the last week we are now sleeping in the cot.
It will pass and if you can use the time to bond, enjoy the cuddles and try to stay calm - hopefully it will help!
