Today is the worst day

I never felt such a horrible mum before. I brought my older son to the playground and the baby was sleeping in the baby carrier. Less than 5min into the playground I fell over as I was trying to retrieve my 3 years old shoe that was stuck and I FELL ON MY BABY! I managed to roll over before hitting his head and I think my knees got the most impact but I also felt I squashed on him. Immediately I retrieved both of them and get to the car, then I called my husband and burst into tears. The LO seems fine but to be sure I had him checked by the GP, and because of this I had to put my 3 year old on video for 4hrs cause my husband needs to work. Thank goodness the GP thinks baby is fine but I just can't stop feeling horrible that there is always one of them neglected 😭😭😭
