My baby had whooping cough at 8 weeks and it was one of the most terrifying things in my life. We didn't go out much either and no siblings but it is so so contagious it only took one person with a cough. Checking she was breathing every 20mins or so night and day for 3 months with several ambulance and hospital visits. If there's any way yo take the jab I would.
I was terrified second time around and stayed in for ages. And avoided children etc as well as having all the jabs.
My ds caught whooping cough in the post natal ward!!. Nearly lost him at 2 weeks old. Suffered relapses of lung infections for ten months due to low immunity and lung weakness . Ten months in and out of children's ward. No fun with other dc left at home .
