Thanks. I did find that thread the other day, and it helped knowing that there are other moms suffering the same fate (and that they got through it).
Ever since I found out that it's normal for them to cry at bed/nap time, it's been a little bit easier to understand and deal with it. We're also trying to adapt to what fits with our lo and so far we've had some better days.
He still doesn't sleep for very long, but already we're stretching some of his naps to 45 minutes (from 30 minutes), and his feeding times are also being stretched every day by another 5 minutes.
Though reading his sleepy cues are still a bit difficult, we're getting there and hopefully he'll have longer awake periods one of these days.
Thanks for all the advise!
