I'm exhausted and it's not getting any better. I've read (or am reading) just about every baby sleep book there is on the market and now I'm more confused than ever. And extremely jealous of those mamas whose babies sleep peacefully through the night. Somehow the thought never crossed my mind that Jackson wouldn't be sleeping through the night by now. Or at least more than a two hour stretch. Things were so good while I was on maternity leave that I kind of figured it would only get better (i.e. he would go from 5 hours at a stretch to 6-7). Nope, not this baby. We're still up every 45 minutes to 2 hours around the clock. He naps for an hour max at a time during the day and is up constantly during the night. Unfortunately all of the books I'm reading offer a different explanation for why he won't sleep. What am I supposed to do? Does a four month old still need to eat at night? Will I cause him psychological harm if I let him cry it out (as one Harvard study states)? All I know is that I need some sleep. Pronto.
