DS (3 and a bit) has always had a dummy but just at night-time or if poorly during the day. He has always been great at giving it up when asked. Last few weeks have seen him become almost constantly attached to it. If I take it off him he gets increasingly distressed and upset. Any ideas how I should deal with this ? Should I just let him have it and hope it is a phase ? Should I take it off him altogether ? btw he is being assessed for speech/social/communication difficulties and tends to just scream, cry and produce lots of tears if I take it off him...
