Hi CR !! I soooo sympathise with you. I remember going through the same thing with my DS when he was about the same age. I think they go through a growth spurt at about 6 weeks??? Could he still be hungry? I guess as well as parents establishing a routine they are trying to do the same thing.

The best thing I found for grumpy bubs is a warm bath - that is my best tip!

I look forward to seeing how you go and hope you get some good sleep soon!
