Letting a baby CIO is cruel and disgusting. You had a baby, now you have to take care of it forever.
This isn’t to say that his needs need to be attended to at the first whimper. He is allowed to cry a few minutes. you can let them cya little bit for them to realize that mommy won’t come running at the first sound.
Sometimes I just calm them down, walk out of the room, and then I keep coming back in to calm them if the crying persists.
But letting a baby cry for hours is just abusive.
7 months old is very young. My kids all woke up throughout the night until they were about 2-3 years old, when they were old enough to communicate and understand when I speak to them. At that point I’d explain to them that I will ignore their crying during the night. I tell them that if there’s something urgent they need, they can wake me, otherwise it’s time to sleep.
No, it’s not easy to be a mother.
