My baby was getting very fussy today
I am sorry to hear about your baby. Does it feel better now?
My wife was breastfeeding someone else's baby, so my baby got very upset.
I'm sorry your baby isn't feeling good, but it has to wait its turn for being fed. In the meantime you need to distract it and make sure it doesn't see the other baby so it won't get jealous right away.
It's okay, my wife doesn't mind. I think it might be a good lesson for my baby.
Usually people want to calm down their crying baby. I don't think a baby can really learn these lessons you speak of.
