Amelia's dad Jeremy Batiz, a 32-year-old contracting officer, had sported a beard for most of his adult life and even his wife Sofia had only seen him without it once before.
"I didn't know that he was going to shave it off that day either," said Sofia, 36, a professional photographer who lives with Amelia, Jeremy and their son 11-year-old Adyan in Tucson, Arizona.
"He just asked me to get the camera rolling on my phone and then he walked out of the bathroom.
"It was a big shock for Amelia and for me!
"Ever since Amelia was born daddy always had a beard, so when it was gone she had absolutely no idea who he was.
"The expression she made was priceless, it was a disgusted face, like, 'eeew get away from me.'"
After the big reveal, 14-month-old Amelia remained appeared skeptical of the "strange new man" in her house.
"It took about half a day before she realised that this strange new man was actually daddy," said Sofia.
The mum explained how her little girl kept "ignoring" her dad and running over to other family members instead.
"He was trying to do all the things that he always does with her, like he takes her out to get the mail with him every day, but she was suspicious.
"It wasn't until he read her favorite book to her that she finally caught on, he always reads it to her in this special way, so she twigged."
