Our dd1 is 2.1.
We have had the Britax eclipse si for her since she was about 10 mo.
Last few weeks she has managed to unclip herself and completely get out of the seat.
The clip makes a small click noise ( but nothing like the clunk from dd2s maxi cosi priori)is definitely fastened and the straps are tight.
What do you think? Is the seat faulty if a just 2 year old can unclip it?
