All valid questions hun and worries that I had as well but just like with cots, there are safety issues you need to watch out for with hammocks, you need to make sure you aren't loading blankets on top, once JJ wasn't being swaddled anymore ( we used to swaddle him as a baby in the hammock - not sure if that is even right but it worked ok before he was rolling) and then we went to using sleeping bags. You want to make sure the sheets that are used on the mattress are nice and firm - and not able to slip off somehow,I made my own and measured really carefully.

I found that when it was time to move him out at around 9 mths old, we just transitioned him slowly into the cot, I used to pop him in there to play with the mobile safely while I was showering when he was really little (to keep him out of DD's way until she worked out how to climb in with him ) just to get him used to being in there and that it was safe. We had no issues at all with moving him into the cot once it was time to do that. There are a heap of FAQs on the Amby hammock site if you look it up to reassure you about safety and why they are so great - Im sure others will pop in with more tips too but maternity wards used to use them a lot as well!! I remember when I had DD they had them there, not sure if they still do now but they should!
