My baby is 4.5 weeks old and will happily nap in the day time without being held or touched etc, at night he will not settle at all without being held or touched or next to me in bed. (He has a next to me cot bed but still not close enough lol) when is it the say they pick up bad habits? At the moment it's the only way he sleeps at night and I'm quite happy to do it but didn't want to get used to it. Would he get used to it at this age?
