@kath26 There’s nothing wrong with you. It’s not uncommon for dads to not feel a connection, or to feel excitement about having a child. In fact, it’s not uncommon for a new mother to feel the same. No one ever talks about these things though so I understand your concern.
Here’s a heads up. The first 6 months are literally making sure your baby doesn’t starve to death or eat something that they can choke on. There’s poop and spit up and sleepless nights and it’s a messy, miserable job. But people expect you to be all happy and giddy about changing a baby who just had explosive diarrhea all over your lap. Don’t fall for it. Mine just turned 1 and it’s only been the last few months that he’s really interacted with us and done anything interesting.
Newborns are boring too. They just lay there. And to try entertaining them… it’s awful. A word of advice, when trying to entertain an infant, they don’t know any better. Have three or four go to activities. A rattle, a swing, a mat for tummy time… whatever. Rotate those few activities. They don’t know the difference. You don’t need to spend 10 hours trying to come up with something new for them to do.
So, babies are boring. Babies are messy. Babies are a long term chore. There’s not much to like about it. That being said, try to distinguish between loving your new baby and liking him.
Also for the crying, learn the art of swaddling origami, then once he’s swaddled, give him a pacifier, hold him in your arms with his head in the crease of your elbow, supporting his body with your arm and your hand holding his legs. Make sure he’s on his side and not his back. Then gently away left and right while shushing him. My wife was amazed at how quickly I could quiet him down. This is known as the 5S technique. Swaddle, suck, side, sway and shush.
