Using the Gina Ford book which has been excellent, however having trouble with the lunchtime sleep now DB is 4.5 months old. Wakes after 30-40 mins and won't go back to sleep without my assistance. Anyone cracked this problem..he sleeps from 9.15 till 10 am, supposed to be 11.30-2 (never happens) and 20 mins in afternoon and 7pm-7am. I know I shouldn't complain but he needs the lunchtime nap as he's grumpy without it!!!
