Hey All my son turned 12 weeks on Saturday. He has been crying alot more and just seems like a different unhappy baby. I read if the 3rd mental leap during this week and the growth spurt. Just wondering if anyone else went through this. Its so so difficult to soothe him once he starts crying. Doesnt help that he is a colicky baby too. I thought the colic was supposed to end at this point! It seems to have started all over again?
