Do you talked about this before the baby's birth? I mean taking care of the baby at the middle of the night when the baby needs milk or change the diapers. I don't like waking up in middle of my sleep but I guess having a family needs me to do it.
We didn't talk about it but we pretty much shared when they were little. Whoever woke up at the time pretty much got up. If my wife had already been up or I had been up, we would wake the other partner and they would get up with them.
