So, after the 4 month regression hell, it all becomes easy?

Please say yes. I need some hope.

In my experience with DD (now 10 months) it got better for a few weeks but she seemed to have sleep regressions every time she was learning a new skill.
We have only just got through another one while she was learning to stand.
On the positive side, after every regression she seems to sleep for a longer period at night (probably catching up!) so I'm hoping a couple more and she will start sleeping right through, which she has only done once.
Sorry I couldn't give you more hope! What I keep telling myself is that it won't go on forever and one day I will get a full nights sleep again!
