You're welcome pr, I've just been through exactly the same with DS1, the same week DS2 was born, DS1 started coughing, not sleeping during the night and then developed v nasty cold. Combined with learning to cope with DS2 and lack of sleep from him too, it made it one of the roughest couple of weeks of mine and DP's lives!
DS2 now has a cold and horrible barking cough and vomiting :(. Had it since Sun and has hardly been sleeping because of it. Aargh. Am praying it is better for Christmas as we spent last Christmas in hospital as DS1 had tonsillitis. kids and their bloody illnesses!
On another note, anyone see the Michael McIntyre Christmas show last night. It was a repeat but the first bit all about life with kids was so true and so funny. Especially the bit where he and his wife don't wish each other good night anymore. Just good luck!
