I would try would be to set up a day/night routine for your little man. They are all just signs that your DS can start associating with sleeping and he'll be comforted by knowing what is happening and when.

Our day time sleep routine would be to take DD towards her room telling her softly it's time for a 'non nighs', change her bott, wrap her up, give her a hug and then we sit in the rocking chair for a feed. She has her feed and generally dozes off then i transfer her to her bed. I realise the feed/sleep part is what you're struggling with but with the other signs maybe the feed/movement won't be such a dependant association for him.

Our night time is pretty much the same... When DD wakes during the night though DH gets her and i lay in bed feeding her, when she's done i put her back to bed. I loooove doing this, it'd have to be one of my most favourite parts of the day but there were times when i think it was getting to be a bit difficult in getting her into her own bed. When she was cleary not settling because she wanted to be with me (which i loved but just needed some decent sleep) i made a point of getting up and feeding her in the rocking chair then putting her into bed.

Your routine can be anything you choose that works for you and DS but i have always found that my little ones respond really well to knowing what is happening and when from the signs that i give them. It takes time to set things up and it takes time to then change them if need be. DD is 8 months old and we've only really settled into something that seems to be working for the both of us in the last couple of months.

I hope this may have helped in a little way. BellyBelly is great for asking questions getting a variety of answers and then arming yourself with a number of ideas to choose what works best for you. Good luck and in the mean time enjoy your hugs
