First Father's Day
Don't stress too much about it though since the truth is that most new dads have no idea what to expect on Father's Day! Depending upon how young their baby is, most new dads may still be adjusting to lack of sleep and not used to being a dad. The first Father's Day can be a way to either show them the appreciation they deserve for being involved or to help give them the confidence they may still need to be a more involved father.
Don't plan anything too ambitious since you don't want to feel too much stress (chances are you're probably stressed out already!). In other words, the first Father's Day probably isn't the time to throw a family reunion/surprise party! In fact, whatever you decide to do, keep it simple— breakfast-in-bed or a homemade card might be just perfect.
The most important thing for you to do is help make Father's Day special for him and your family. Let him know that you're thinking of him and appreciate all that he does. Cater the day's plans to his interests. Does he like to barbecue? Does he like movies? Music? Other events? Maybe Father's Day can be devoted to those things he likes, especially if the things he likes are activities that can be done with your child so he can begin sharing what he loves with his new love.
