anna i just wanted to add- try (i know it's hard) but try not to listen and compare yourself to others. it will end up doing your head in. i remember when ds1 was a newborn, rocking up to mothers group and having a mother tell me her baby slept in his cot every night from 7pm-7am. i came home and i cried and cried, questioning what i was doing wrong. why my baby woke constantly all night long.
you'll be happy to know that ds1 now (19 months) sleeps 8pm-6am almost every night.
