Sleep training experts!
LO wouldn't nap till 2.30pm whereas we trained him normally to do 1-3 for a 7pm bedtime.
Our consultant told us he can't sleep past 3.15 so now he will only have 45 mins of sleep! Do I wake him up after 45 mins and bring bedtime forward to 6pm?? How does this work please? 
He is 8 months in a few days...
Morning nap was 45 mins
TIA!
