i turned my dd at 7 months and 9kgs , i think i might have a similar seat .
Having been in an accident when maya was 10 months old where i hit a cow in the middle of the high way on a blind crn , she was in no way harmed and the seat did not move and it was only the noise i think that made her wail . i of course replaced the seat then , but i like some one else up there found she was at the edge of it and un comfortable and stoped screaming cause she could see me the min a turned it .
i didnt walk away from my acident i had to be cut out , by dd was fine not even a scratch . i have a Baby Love seat
