I was like you, she slept on my chest, when I started her onto the routine, she slept as well as on my chest. That was me who missed her sleeping on my chest :lol: . She had always slept in her moses basket at night, so she was used to it, so that wasn't that difficult to help her get used to her naps in their as well.
It is good that your DS is awake when you put him down, so that he knows this is the place he goes to sleep.
But the hardest part of all, was when she outgrew her moses basket, so we had to put her into her own room, I put it off for about 3 weeks because I didn't want to be apart from her :oops:
There will be difficult days and better ones. You will soon get used to it, but hang in there and make the most of it, because they soon grow and the lo's won't want you there so much, as my DD is now starting to do.
