Ann I think you sound like you are ready to get tough . I would start by waking him at 7.30, brekker, play (preferably physical to tire out), lunch, nap (pushchair or cot) for at least an hour, play, dinner, bath, story & milk, bed 7.30pm. If DP is not getting home until late then there is no reason to keep Seb up so he sees Daddy. We are all here to help you through the first days of a new regime, but you need to decide how your day is going to pan out and really go for it. We will be cheering you on
Steaky - well done on the minimal interference settling and good luck with deforestation
