So, DS night back in his own cot did not go all that well. We had our first ever night of vomtasticness. I know, I know we have been soooo lucky to get to 13 and a bit months without having to deal with this.
He fell asleep on DH after dinner so was put down in the cot. I went to bed shortly after. I woke when DH came to bed at about 11.30. Not too sure about the times after that, but we both heard him coughing a bit. Which then stopped. And then started again accompanied by a wail. DH went up to him and said he could smell the tell tale aroma half way up the stairs 
I think this was about 1.30ish. DH and DS had a shower as he was covered (he'd obviously been sick with the earlier coughing
bad parents ) and I stripped the cot, rinsed the sheets and put them in the washing machine.
By the time I got back to our room DH had DS in a fresh nappy and onesie and they were cuddled up in our bed. With a bottle of milk. Oh my, what foolish first time parents we are. About an hour or so later the now curdled milk was rejected by DS's stomach all over our bed.
So the boys had another shower, I stripped and remade our bed and dumped all our sheets in the kitchen.
DH took DS downstairs so I could try to get some sleep, but I obviously spent a good hour on MN as was wide awake before drifting off for a while and then waking up at 4.30 when I heard DS being sick again....time for me to get up for work anyway 
Oh well, he's next door with SIL at the moment, I got home from work nice and early so have bleached the floor where he was sick, put in another load of smelly washing, washed and steralised everything he ate from yesterday.
Off to disinfect the cot ready for another try tonight.....
