Hi, I have a 5 week old baby, our first one! He has been upset for a week or two, Colic symptoms. Pulls up his knees, crying in pain, then lets gas go and is okay for 20 mins or so, but this can continue for a few days. To get him to sleep at night I comfort him and then put him on his tummy on my chest, after a few rough days this is what helped him to have a decent sleep as he was exhausted from pushing out gas down below. Are they able to sleep on their tummies in a cot or bassinett? I know it is not recommened, but he seems more comfortable and settles better when he has these rough days. Any advice would be great. Have also changed teats, thought he may be getting too much air in.
