Hi there!
my first problem is that it is very hard for me to make a schedule and stick to it when every nap is a different length.
Okay, first, I think it's important to remember that we're aiming for a routine here, not a schedule. The younger the baby is the more likely it is that your times will vary from day to day (because there are just so many variables that can affect them and because they change so darn fast at this age), but you keep the sequence of events predictable in the EAS pattern. You're not trying to reproduce the same schedule each day, just a predictable routine. Trying to schedule a baby is likely to create very unrealistic expectations and a lot of frustration for both of you.
so do i always wake him by 5pm even if he gets a short nap so that he can have time for another catnap before bed.
Based on what you're describing, for now, yes, I probably would wake him in order to preserve the late cat nap and keep your feeding routine rolling as well. It's likely that in the next 4 weeks or so your baby's evening nap needs will change, so at some point you'll have to experiment again with changing that, but if for now it's working best to have a late cat nap, then I would preserve it.
i would say that 2 nights a week, we have random night wakings. he has several times gone from his dreamfeed at 11pm till his waketime at 7:30am so i know he is capable...however twice a week, sometimes 4 or 5 nights in a row, he will wake up randomly. once he wakes up once he wakes up, i give him his pacifier or will let him cio and he will always fall back asleep within 10 minutes of crying, but will continue to wake up every 45 minutes until i feed him at 6:30 or 7am. i guess i just don't know what to do since cio doesn't work. why is he waking and what do i do when he wakes every 45 minutes? i don't want to feed him since i know sometimes that he isn't waking out of hunger.
Okay, so as I read this a few key things stand out to me. The first is the word "random." Because of your LO's age and because these wake ups are random and not at an habitual set time, I'd suspect that they are driven by hunger. Just because a baby can go one night without eating for 8.5 hours, doesn't mean that you can count on him doing it every night. 14 week is still very young and it is very common to have a dream feed plus one more night feed. At this age, if it's been more than 3 hours since his last feed, I'd be inclined to suspect hunger and go ahead and feed--particularly if you are breastfeeding. If baby is waking because of hunger, that would explain why he wakes repeatedly--if he woke hungry once and wasn't feed, when he transitions to his next sleep cycle, he's likely to wake again because of the unresolved hunger.
Secondly, you mention offering the paci to resettle. It's possible that the paci has turned into a prop. Can you describe how your LO falls asleep at the start of the night? Is he going into the crib awake or asleep? If he's going into the crib awake, are you in the room when he falls asleep? If so, are you touching him (patting, etc)? Singing or shushing, etc? Does he fall asleep at the beginning of the night with a paci?
Finally, you mention that for some night wakings you are leaving him to cio. As you may know, Tracy Hogg, the baby whisperer believed that a baby's cry is his own only means of communication and it's important not to ignore that crying in order to build and maintain trust with your LO. She believed there is always a gentler way to teach baby to sleep than using cio. At 14 weeks, the primary baby whisperer sleep training tool is shush/pat. Check out this post for more details about how to use shush/pat:
http://babywhispererforums.com/index.php?topic=26672.0Tracy did make a distinction between a "mantra" cry, which is a fussy self-settling cry that tends to be rhythmic and does not escalate. This mantra cry is sometimes part of a baby's self-settling process and if that's what your baby is doing, it's okay to hang back and see which direction it goes. However, if it turns into a genuine "I need you" cry that escalates, the baby whisperer would recommended responding promptly and using shush/pat to help your baby settle in the crib.
{{Hugs}} I know this can be really frustrating when you're trying to figure it all out and do what's best for your baby. Try to relax and listen to your LO's cues. He's just a wee thing yet and will still need your help figuring all this out.
