It sounds like holidays aren't the problems. What you actually seem to dislike is parenting. That is to say, it's not the lack of work, it's the lack of someone else raising your child. Framing the question correctly may make it easier for you to find the answer. Parenting is difficult, often much more difficult than a professional job. You can find ways to trade naps and late nights with your spouse, and find ways to incorporate your child into things you enjoy doing to ease some of the strain. Reality is that life as a parent is different than life only taking care of your own needs. It's not going to be the same, and hopefully you realized that when you had a child. A certain amount of dealing with this is going to be accepting that and learning to be ok with it, or even happy about it.
