I am still very much for a change of the Halfling model. And i really hope that larian does not ignore this.
No matter what anyone says about "not beeing mistaken for a child", i agree with Ragnarok on this. Ofc it can. Personally i don't really see an issue with that. There are normal adults in RL that can be mistaken for children and some children that look far older than they actually are. Nowadays there are 13 year old that have a bust size of C and bigger.
I have read novels where halflings actually want to be mistaken for a human child. Especially Rogues
