Hey,
my Boston's 14 mths old and he still suckles on a particular blanky that's 'his'. I think it's just a Boston Terrier behaviaour, and not that they were taken from their mom too early. Mine was 10.5 weeks old when I picked him up. It's super adorable, but he has a habit of making really weird noises when he suckles. They used to be pretty loud, but we've managed to make him stop (most of the time anyway)
