OMG yes - MIL has been doing this since DS was born. As others have said, I apparently have had no genetic input into my child at all
I think the best one that I can remember (there have been so many) was that DS has always been unable to keep socks on since he was born - at first he rubbed them off, now he just pulls them off - which of course, is exactly like DH was. It takes all I can do to not shout at her 'no, you silly woman, it is just what babies/toddlers do!'
