First time mum dealing with daughters seizures....

Hi, I am after some advice about my 16 month old daughter. About 2 months ago she was taken into hospital after a choking episode and had to receive first aid to get the food out of her throat. This was obviously very traumatic for her (and the rest of us!). We were discharged from hospital after all tests were fine and returned home. A few hours later my daughter had a seizure. Scariest moment of my life! She collapsed, went blue, jerked and was absent for a good 10 minutes afterwards. So we went back into hospital..... and then she had another one that evening. Following these episodes she was kept in for tests and observations for 3 days. All came back clear and we were left with no explanation. Still not sure if the choking incident was infact a seizure aswell, or if it was what sparked the following episodes. Anyway, we are going to be under the consultant for atleast 6 months to monitor the situation. Now as you can imagine this has all made me a bit on edge as a mother and I now don't know if I am reading into things too much... but for the last few nights her sleeping has become really bad and she keeps waking up very upset. Last night we had her in our bed and noticed that each time she woke up it was after quite a big jerking movement and then a shriek that doesn't sound like her normal cry. I am a first time mum so not sure whether this is normal or whether it could potentially be a seizure? Does anyone have any similar experience? She doesn't seem herself today...she is very tired and clingy. Thanks for any help in advance! Holly
