"Both of you are going to be wonderful parents jessa [sic]," stacey.mcmahon.35 shared. Another fan, hopingfortheday97, shared similar sentiments, writing, "I can't wait to see how Ben reacts to his baby. Y'all will make amazing parents!"

While most fans are excited about the post and agree that Ben will be a great father to baby Seewald, not everyone feels that way, and critics have picked apart the fact that he is young (and his style reflects that).

But the negative backlash is upsetting a lot of fans, who were quick to come to Seewald's defense.

Another fan agreed, writing, "just because he is going to be a dad doesn't mean he can't where [sic] a hat my dad is a father and he wears a hat every day of his life and u don't need to use false language on this Instagram account," wrote katie.haney.
