I have a three day minimum as well .... However I wouldn't coddle him at all .... If he's crying I would put him in an area where he can cry for as long as he wants .... I would tell him " sit there till your happy and ready to play with us " and then walk away ... That way he is in charge if his own happiness. By cuddling him you are feeding into the crying. If he's constipated bake some bran muffins with raisins in them and give them as a snack to help get things moving as well as lots of fruit .... Otherwise give him the food you are offering and that's it ... He'll get used to it and the crying will get less. You might suggest having him a few more days a week for a month or so just to get him settled.
