Thank you, lily_layne!
Yes, we need to work on independent sleeping - as soon as my DH will be done with his work project (two weeks left).
I actually was looking for a PU/PD forum, but I can't find it anymore. I wanted to ask some questions regarding PU/PD implementation (for example, what if it is time to eat and PU/PD is not working) as well as read others successful stories as an encouragement.
