Personally, I like to share and get people's opinions. Just because you hear them, doesn't mean you have to listen .
There can be things that you might miss or not pick up on, but that other people can. I have a friend who had a child whose name in full sounds fine - but when you use the nn with the surname sounds a bit odd (similar lines to Ben Dover). She never announced the baby's name until after the birth and of course, at the time we all thought this nick name, but presented as a done deal, nothing could be said. Roll on a few years she is now moaning that her son's name gets laughed at and so on... we could have told her that years ago, but of course it is too rude once the baby name cards have all been sent out etc.
Equally, there were two names that we were considering for my daughters, until the midwife for DD1 pointed out it sounded a bit like a drug. I hadn't thought of it, but she was completely right and one of the names we were considering for DD2 sounded lovely as a full name, but if you put one of the nicknames with the surname, then it made a word, and not pleasant word that you can get away with. So that name was trashed too .
So yes, I do ask - it can help you to avoid making a terrible mistake, but I only ever half listen - if its just a personal opinion, then I'd ignore it - we all have pet names that are perfectly nice but just not to our taste, but on the other hand, if a name has a connotation, I would want to know that because if my child had that name, and it is a common connotation, then I wouldn't want to give my child a name where people might hold those connotations against that name iyswim!
So I ask, but also freely ignore
