An awesome video has emerged of a father giving his baby his mother's dirty shirt to make him stop crying. <br /><br />The footage, shot earlier this month in San Francisco, CA, USA, shows the three-month-old boy immediately calming down as he smells his mother's smell on the shirt. <br /><br />"I was watching him one day while mom was running errands and he got real fussy," the father wrote online.<br /><br />"Another dad-friend of mine suggested placing one of mom's dirty shirts from her hamper on his face, so he could recognise the smell and calm down."<br /><br />"I had no idea it would work so well! I hope this video is shared enough to help another dad out of a fussy situation with their little one," he added.
