I think that generally speaking men need to be coaxed into new ideas, especially "touchy feely" ones. That's been my experience anyway. Maybe you could try asking for a week to show him that your way is working. He might go along with a temporary setup even if he disagrees. I agree with you about being on the same page. It's really confusing to kids, otherwise.

You could try using emotional intelligence coaching on your husband! He needs to be heard too and his opinions respected. I think that everyone has their own parenting style and one family can accommodate this. As long as parents want the same thing, ie their child's happiness, success etc, I think it's ok for them to parent differently. 

If your system was perfect he would follow, if his system was perfect you would be on his page. Disagreement usually means neither are on the right tract. Sometimes the parents need advice to work together about parenting. Sometimes even perfect parenting  will not work if the child has a`problem .Then the parents need to see a professional to solve the  child's problem and then hand over to the parents with insight and sympathy and knowledge. Some children need to be made more teachable for parents to succeed.
