If you are happy with it at the moment, I'd honestly say keep doing it. The hammock idea is a good one as a replacement (I have had all 3 of my babies in a hammock, so I am a big advocate!)

And the suggestion from Astrid re music is a good one too.

They are little for such a short time, honestly, if you are happy to rock Nicholas , rock away!

but am I going to regret it later on?
Only time will tell I guess. I know that with Olivia I worried all the time about setting up "bad habits" for later, but my fears were pretty much unfounded! She was rocked to sleep for the first 4 months of her life, then SHE decided she didn't want it any more, so I popped her into the hammock awake with music on & she would drift off........(so my earlier fears were unfounded...........)

Nicholas may adapt his own habits all by himself?

Charlie STILL likes to be rocked before bed, all 16kg of him, LOL! (I love it too.....that solid little body all snuggling up to me, with his face in my neck!)

Sorry sweets, I probably haven't helped much, but I say go with what feels right for you both at the time......
