And what do you/they do in the meantime?
I did gradual withdrawal with ds1 when he was 12 months old, to the stage where I put him in the cot, switched mobile on and left the room. It took 10-20 minutes for him to fall asleep. I would hover around to reactivate the mobile after ten minutes as he'd rouse and get up if he wasn't asleep when it turned off (after ten minutes) I was OK doing this. I now have ds2, and ds1 bedtime took a major setback at the time of ds2 being born. His dad was putting him to bed as I had several nights in hospital leading up to the birth and some after, and he was cuddling him to sleep on our bed then transferring to cot. It's taken me ages to get back to him falling to sleep in his cot nicely, but I've put off leaving him. Now though it can take 30-50 minutes. So I'm doing GW again, but I can't really be hanging around to faff with the mobile.
So just wondering what others do - put in cot and go downstairs? Just leave them to it? Do they play, look at books in the cot?
I have a different 30 minute mobile I could use but maybe should be weaning off the mobile.
He has a nap with the radio on low, but not keen on this for bedtime.
