I feel like the worse mom ever... I was rushing into the grocery store with my son ..who was in his carseat strapped and i put him on top the buggy..normally take him out but its was pouring... Quickly shopped and after i paid...we were heading out ...i didnt go down the ramp...i went over the curb..lost control of the buggy...his carseat flew off with him in it and landed upside down in the parking lot... I was on the ground and rushed to him..people swarmed around us...he was perfect...shocked but no scratches no bumps... Everyone kept asking me if i was okay and all i could do was hold him and cry... How could i think going over the curb was okay? I wasnt thinking..i let other things go through my mine before his safety... I cant stop thinking of what could have happened...it was the worse moment of my life 😢
