I just tried the self settling thing at 9am and went in everytime Brianna cried to pat her. If the crying increased I picked her up, settled her until calm and put her back down. It took 3 times until she was calm enough to hang in her cot awake. She fell asleep about 3 minutes later and is still asleep. Now the test is to see if she will settle herself at the end of the first sleep cycle. Lets hope so

Debbie - Maybe you could place the cot in a position in Aidens room so he isn't able to see too much of what is going on. I have Briannas cot in a position where I can see her from the living area up a mini flight of stairs and it doesn't seem to bother her. The door is open all day and night and the noise wafts up, day and night. She sleeps through it all and doesn't wake due to the noise / activity factor.
