Help! My 11kg skinny 3 yr old daughter has worked out how to get her arms out of the straps of her besafe izi combi. She was howling today that the straps were too tight and hurting her shoulders (pulled as tight as they possibly could be and I think pulled as short aa they will go as she was only in a thin t shirt and leggings) and then mid tantrum as we were driving along with her howling her shoulder hurt and the straps were too tight, she got her arms free. Cue emergency stop and a sound telling off from me. Strapped her in again, not physically possible to get straps any shorter/tighter and she got an arm out again 5 mins later. More shouting and she apologised and said she wouldn't do it again but I am now worried. She goes in a kiddy guardian in DH's car so we could simple use that seat from now on but I feel she is safer in the besafe whilst she still fits in
