4 yo DD has recently really got into doing jigsaws. She does ones with fewer pieces on her own, or big ones with me. Clearly she is influenced by the way I do them - which is to start in the middle, or at a particularly colourful bit and work outwards, and do the edges last. (I've always done jigsaws that way, and I think it is easier as the edges are usually sky/tree whatever and harder to match together.)
Yesterday I had a few people round and DD was doing a jigsaw on a table in the corner of the room. Every single person went over at some point to help her (sometimes she had asked for help, but not every time) and they all told her she should start with the edges. Several people said to her "Don't do it like that", or other phrases implying she was getting something wrong, and one even said to me "she needs to learn to do it properly at some point".
AIBU to think that there isn't a "proper" way to do a jigsaw, that the way she does it is just fine - and even if it wasn't, she is doing it for fun, and they shouldn't suggest to her she is doing it wrong?
