Mum confused as husband ALWAYS wants her to sit in the back seat of the car

We're not sure about this one.

On one hand, when you're child gets used to something, it can be hard for them to break that habit. But, it's also good to break a habit if it's unhealthy or simply not needed. That's this mum's problem. Since her child was born, either she or her husband would sit in the back seat of their car along with their child. However, their child is now 4-years-old, and she thinks the habit needs to be broken... her husband doesn't think so, though. In a forum on Mumsnet, the mum reaches out to fellow mothers to ask if she's being unreasonable to go against her husband's wishes. She said:

"DH is still pretty insistent that I sit in the back seat, mostly to ensure he stays awake during the car ride and not disturb with the bedtime schedule. But can insist at times that doesn’t impact bedtime, as apparently it’s just ‘easier that way’. "If I refuse, he’s been known to leave me in the passenger seat and for him to sit in the back - forcing me to move to drivers seat. My point is that DS is now old enough to sit in the back alone, so him moving is not helping. "DS has now got use to someone sitting with him all the time, and can become insistent that someone does too."

Many users replied to say that no, she's not being unreasonable and should stand her ground:

"This is ridiculous! You need to speak to him at a time when you aren't about to get in the car and find out what the real reason behind this is. Maybe he is particularly anxious and thinks son will be safer with someone with him? What happens if you don't all go out together? "One parent drives and son in the back? So why does someone need to be with him in the back just because you're all going out together?"

While another wrote:

"What other things does your dh indulge your ds in? He sounds over anxious. Your dh, not your ds. Ds is just taking advantage of the situation. You can't blame him."

What so you think she should do?
