Yesterday while sitting with my niece she was eating French fries and her shoulders went up and face turned red I snatched her so quick from in front of someone els turned her upside down and started to hit her back. That was the second most scariest thing to happen with me being around a child.... I am certified in both infant and adult CPR as well as first aid.... Lord knows my poor baby boy on the inside could hear my heart racing I still was panicking on the inside but thank God she was okay 😯😯😯
