Yeah growth spurts are transitional seasons which usually lasts for about a week and I would assume most babies will go through it. You can read more about growth spurts here: kellymom.com :: Growth spurts
Can understand how you feel when baby cries until cough... But dont't know .. I also scared I give him too much attention then he always pull the same trick. So my fear of that actually stops me from giving him too much attention. I know not all mummies here agree with what I do and some believe that you can never spoil a baby. So you would really need to do your own assessment of the situation.
The routine I put my baby through is not easy at times and sometimes he does get fussy and throws a tantrum. But this time you fail, next time, you learn better. So it takes a few weeks of trying to stick to routine for the baby to go along with it. I think you're doing well so far though.
