When choosing a shirt for your baby, think about what he will be wearing most. If he is going to be wearing a shirt all the time, choose a soft, comfortable one. If he is going to be wearing a shirt only occasionally, choose something that is more durable.
Another factor to consider is the size of the baby. Most baby boys wear size 1-3T shirts, so choose a shirt that will fit him well. If the shirt is too large, it will be too big when he grows out of it. If the shirt is too small, it will be too tight when he grows out of it.
Finally, think about the style of the shirt. Most baby boys love superhero shirts, so choose a superhero shirt that is appropriate for your son's age and interests.
