Using 'cry it out' with daytime sleeps....?

How does he sleep at night? I was just wondering because my 5 month old son has the same napping patterns as your son does. He takes 3-4 40 minute naps a day just a few times has he slept for any longer sometimes I only get 25-30 minutes out of him. At night he will only go 1.5-2.5 hours before waking up to be lulled back to sleep. Only once or twice in the night does he Truly want to feed. I am exhausted LoL! seems like your question has turned into a question from me. I have tried cry it out also it just doesn't work he crys until he is gagging!! :( So I feel for you makes me feel better that I am not the only mom out there dealing with this problem!
