Around 46 weeks is a really big wonder week for the little ones where their brain does a huge leap in dvelopment and often this can cause disturbed sleep and clinginess...Connor had similar issues and we just perservered and got over the hump eventually....he has gone back to having naps...we do rock him to sleep during the day though and then pop him in his cot which he seems to like....at night he goes straight in the cot no rocking but he seems to like the cuddle time for his day sleeps, it must help him to wind down or something.
