Yasin has a blankie that he loves. It was his wrap when he was a baby and he's still using it.
I found it really usefull because when he's a bit stressed out (like his first day at childcare) it helps him cope and when I want him to go to sleep it's a great trigger. I give him blankie and he will start to wind down straight away.
Luckily for me blankie is actaully 3 blankies because I had a pack of 3 so I can rotate them and if 1 got lost it wouldn't be a catastrophe.
If your bubba only has one blankie it might be worth cutting it in half and hemming it so that you can rotate it for cleaning and so that if one gets lost it won't cause so much drama (if you lose one you cab cut the remaining one in half lol).
He also uses a dummy at bedtime.
Now that Yasin is older he's expanded his range of comfort objects - now he has ted bear and quack quack and I have to say goodnight to them every night.
