A Sleeper?

I thought we really had a decent sleeper on our hands with Ronan. We were really excited about it since we struggled with Archer's sleep issues (and still do). But I think we spoke too soon...

Ronan slept well for the first 2-3 weeks, and I will now attribute that sleepiness to being worn out from being born. Ronan now sleeps about an 1-2 hours at a time during the day. If we are lucky, at night he will sleep for 3-4 hours at a time. And he enjoys being awake from about 3am until 7am, just in time for mommy's shift! I have noticed that he will also fight sleep, which is something Archer does. Ronan will start to drift off and then wake himself back up again. Ugh. Will we resort to "Ferberizing" this baby and letting him cry it out? Or will we resort to some hippie-dippie "family bed"?
