HI A.,
I see you got some great advice on the crawling.
My daughter was also one of those babies who woke up a lot during the night, still does.
Now that she self-soothes, she's 16 months, she sometimes cries a little and I just go in to lay her back down and she's fine.
Other times she just cries a little and goes back to sleep.
My son sleeps soundlessly at night, I have NO IDEA. Maybe a personality - lighter sleeper, more sensitive to sounds, who knows.
Also, she got GERD, which causes really bad heartburn but even after treating it, she is still one of those constant wakers.....
Maybe you can still run it by your Dr. I did have to get very strict about not feeding her at night.
You could end up doing this until he's like 16 months, I know women who can't put down a rule and end up doing it far too long.
When she didn't know how to soothe herself (until around 8-9 months) I had to go in and pat her butt or caress her, tell her to go back to sleep etc... sometimes not talking is better and just reasure them, there is also the optionof letting him wake up, cry a little and use this as an opportunity for him to learn to go back to sleep on his own.
I belive in nurturing and not a fan of the CIO club but sometimes you have to let them learn to relax and go back to sleep...

Wanted to add, the excersaucer etc, IMO if not used in extreme excess won't hurt him, he may be a late walker or just skip the crawling. I had daughter in a jumperoo, swing, bumba, bjorn, I was pregnant when she was 3 months.... and she still walked at 10 months so there's no rule, IMO ;)
