I have baby in front with me so they can see me, helps slightly
If it’s too distracting find a safe place to pull over. Depends on how long the drive is ect, but there isn’t much you can do. I put music on and sing and that 9 x out of 10 works - he must think my singing is so bad he’d rather go to sleep and not hear it 😂 You know your baby best though and their cries and what you feel comfortable with x
I deactivate the front passenger seat air bag and have my youngest in the front and my toddler in the back. Before leaving the house I change baby and feed him to reduce the likelihood of him becoming unsettled when out.
Not much you can do unfortunately, if you still have a bit of journey to do then you could stop somewhere and settle but for everyday short journeys, It's just one of them and will grow out of it. Maybe play white noise (if you have Bluetooth on your car)
