Hi
You could try putting a few dummies in the cot, we had about 5 on the go at one time! However, it means that if it falls out and on the floor, there's another one ine there.
We are a few months further down the line and Johno is sort of self weaning. He's only ever had the dummy in bed, he has it to go to bed and I presume he sometimes wakes and puts it back in. However, he almost never has it in his mouth when I look on him when we go up to bed and never in the morning, never when I go to wake him from a nap.
The other day, he put one in and instantly took it out and said it was yucky, put it in the bin. I looked at it and it was split so I did as asked and put it in the bin. We haven't replaced it. I've also noticed that he gets fed up with it when we are doing stories in bed as I can't understand what he's saying so he keeps taking it out to talk and often doesn't put it back to go to sleep now.
