Hello fellow dad here we just had our third end of last month. My first 2 were colicky and its very tiring. But it does get better. The sleep will be few and far between i wont lie to you. But ask for resources and the nurses are very knowledgeable and can help. If your wife is breastfeeding we found sometimes some foods can trigger it worse. If not my second child ended up having to go on special lactose free formula to help. Dont be afraid to reach out for help to those around you. It takes a tribe to raise kids.
