Zoe and I are messing around. I thought it would be funny to tickle her as she's soooo ticklish! She is such a drama queen though squealing loudly and begging me to stop as she laughs hysterically! She stops laughing and goes silent begin to struggle a little, at first I continue to tickle her and laugh at her thinking she's putting it on to make me stop. She grabs hold of her chest and falls to the floor. Still laughing I tell her to stop being silly and get up. I get onto the floor to shake her and realise she's actually not breathing!!!! I panic and begin CPR. I give her chest compressions and mouth to mouth as I cry to her to wake up. Its so tiring but i keep going as panic really begins to settle in. What have I done?!!!  She is still not moving so I take her top and bra off so I can check her chest is rising correctly. Finally as she begins to stir after what seems like forever doing CPR I put her in the recovery position and go to call an ambulance!
