It has become more and more evident to me since DS was born that DH and I have wildly different parenting styles.

I lean wayyyyy to the side of attachment parenting, whereas DH believes in being extremely stern, CIO no matter how young, spanking when DS is old enough, and that at 3 months DS is perfectly capable of playing alone with long periods of awake time (30 minutes). He also believes that that DS needs to self soothe to sleep, even if he's crying his eyes out. Yesterday he got on to me for going in the room and rocking DS back to sleep because he woke up crying.

After the video @Espion just posted, I can't take it anymore. I just can't deal with his parenting style. I have done a TON of research and read a lot of books that lead to the decisions I make. He just does what he thinks is 'best' (i.e., easiest for him). He's never so much as read a pamphlet. He calls me all frustrated because DS won't do X, Y, or Z... but he won't try MY way because he says its 'spoiling'.

What can we do to get on the same page?
