When you have your first baby nothing will have prepared you for the havoc that baby will wreak on your sleep. People talk all the time about how little sleep parents of newborns get. People say silly things like, "Sleep extra now while you can" or "Store up lots of sleep before the baby gets here." If you are expecting a baby, you will be warned many times about the sleep deprivation in your future, but you won't be prepared. Nothing can really prepare you for not sleeping, and nothing can really fix the fact that you will go through those first few months with hardly any sleep to fall back on.

Of course,
it does get better. But while I'm guessing that no other phase is quite like the first couple months, parenthood in general is not a time of carefree, plentiful sleep.
Almost four months ago I wrote this post:
Sleep Training - Yes or No? Four months ago I had a sweet little baby who was capable of sleeping for 7 hours at a time, (or going 7 hours without nursing), but could not put herself to sleep at all. Every single time she woke up during the night she cried, and either my husband or I would have to get up and help lull her back to sleep. Then when she did fall back asleep, about 90% of the time, if you set her down in her crib she would wake up and continue to cry.
It was hard. We talked about sleep training daily, but we didn't want to do it. Like I discussed in my post, it didn't feel right for us and it didn't feel right for her. We ended up coming up with a somewhat awkward co-sleeping arrangement involving the couch, my husband and I not sleeping in the same bed for a while, and our daughter essentially being held all night long while she slept.
I was so embarrassed that I couldn't get her to sleep in her crib.
