Has anyone purchased any of the TCB courses? My 4 month old wakes 2/3 times a night for a bottle and has short naps in the day! Me and my husband don’t know what to do anymore as we are just tired and miserable all the time! Lots of the reviews say how good it is and how their babies are now sleeping 10-12 hours a night! Not sure how genuine the reviews are. Any advice is much appreciated xxx
