I'm planning a few evenings out and wondering how my DD will cope! She almost always falls asleep with a boob in her mouth, and I'm not sure at what age I should try and 'train' her out of this, if at all. I don't want to resort to using a dummy, but will she be distressed if I leave her for a while? If any mums have some advice or personal experience to share, I would love to hear, thanks!
