Can I sleep at night while my wife takes care of our newborn?
Why do you want to sleep while your wife takes care of your baby?
Because I need to get my beauty sleep
I am sure that your wife would appreciate it if you did your fair share when it came to the baby. While I am sure you are very tired, just do your best to make sure your partner has time to rest as well.
I understand I cannot rely on my wife to change the diapers in the middle of the night and take care of the baby.
It is great that you understand this. Sharing the duties equally will probably be the best way to ensure you are both getting some time to rest.
