Questions about safe t sleep

I have had trouble accessing old posts about safe t sleeps so not sure if the following q's have already been answered.

I am thinking to use the safe t sleep we were given when we had Jack (finally) as Ben is starting to get a flat spot. I have the following q's:

* do you safety pin baby to the wrap like the instructions say?
* how do you combine the safe t sleep and a swaddle wrap? The instructions say to have an arm out but that seems to defeat the purpose of the swaddle
* how have you found using a swaddle and safe t sleep with side sleeping? With the swaddle it seems that Ben would end up sleeping on his arm which doesn't seem comfy.

TIA!!

we have used a safety sleep with DS since he went into a cot at 3 weeks cos he shuffles up the cot and gets all kinked and bunddled up the top. he wont sleep with his arms wrapped so they are both out so he can wave them round and munch on his hands. lol. DS also tends to look in one direction no matter where i move his cot, and has developed a flat head on one side, so during the day plunket has us sleeping him on his side. we have 2 towells rolled up, put him on his side so his arm is out in front so he can flip and put the safety sleep around both the towels and the baby. its look hilarious but it keeps him off the flat spot and stops him rolling right over

we used it mostly for my piece of mind and for his flat spot..no idea how it fixed it but it did..? weird.. he got way too hot in the sleep wedge and I was paranoid having him on his side.(but this is supposed to work great for flat spots)

Thanks ladies. Mum bought me a wedge yesterday. I was thinking to use the wedge in the bassinette and the safe t sleep in the cot as he will sleep in the cot during the day but think I may just use the wedge. Was only thinking to use the safe t sleep as we were given it as a gift when Jack was born and I have never even taken it out of the packet!!! Feeling a bit guilty about that

I really like the idea of a safety sleep... but I was wondering how disruptive the sound of the valcro would be at night if I was trying to dream feed?

Advice anyone?

will depend on bubs personality, and how tired they are. but my boys can stay asleep while the velcro is undone and a nappy changed - or they can wake the instant you open their door. just depends.
neither of my boys have 'dream fed' in their sleep - they have had to be roused a litlle in order to feed, but drift back off to sleep either on the boob, or once tucked back in.
