The best thing you can do for your child's outcomes is ensure you also have a life outside of them. And they should be aware of it too. "Mommy and Daddy are going to have some fun with thwir friends so youre going to have a sleepover at Grandma's tonight!" and if they cry, tell them to suck it up. It will teach them independence, that their mother is not an appendage of them, and it will help them develop their own sense of self seperate from their parents. Its also not a good thing for overall parenting if Mom is stressed to the tits because shes never taken a day off or time for herself. A relaxed and contended parent is a better parent. Its also good for your relationship with your husband to get out just rhe two of you and have adult fun once in a while, and that also has child rearing benefits. Parents who still have rhe spark because they also prioritize their relationship in addition to their parental duties are is a much healthier environment for a child than parents who have become strangers because they haven't seen each other as anything other than co parents in years. It will teach your child that they are not in fact the center of the universe, this is a crucial lesson many children these days never learn, to their great detriment as adults. In short, not only SHOULD you go to this event, but you should be REGULARLY going to these kinds of events with your husband (at least once or twice a month). Youll look forward to it for weeks and it will improve your relationship with your child because it gives you the opportunity to miss them. It is far more in the child's best interests to have happy, healthy parents with a happy, healthy relationship than it is to be in close proximity to a parent 100% of the time. In fact, being in constant close proximity to a parent 100% is actually harmful for your child's mental and psychological well being, they will become dependent and their emotional development will become stunted. They will be incapable of perceiving themselves as independent, capable and resilient human beings, something all healthy well-adjusted adults need to be able to do.
