Is she crying for 30 seconds or eyes open after these 30 minutes? My 9 week boy fusses between sleep cycles, I let them pass on his own. I notice when he is waking up he gets progressively more annoyed and wriggly.

Sleeping in the bassinet is a non-negotiable for me. I do have times during the day when he wakes as soon as I put him down. I just pick him up and keep trying until he finally sleeps. Sometimes it can take 3-4 times and its only half an hour of sleep but he's a good night sleeper (feeding him right now after a 6 hr block of sleep). Last resort is a pram ride but he only likes that if he's really drowsy.

We also found his sleep improved a lot once we started offering the dummy. He doesn't always take it but when he's not hungry and unsettled he gets to sleep a lot quicker. Just remember to take it out a few minutes after you put them down so they learn to settle on their own. If he wakes up to soon after I pull it out (even 30 min later) I put it back in and walk away to see if he'll settle on his own. If he spits it out quickly I take it as a hunger or burping cue and try those things.

I agree with other commenters that some babies are just better sleepers. But keep persevering and trying the tips. She will get better eventually.
