Funny you should ask this we do this with my DD and over the last couple of days been thinking about whether I should be trying to stop this. I have no prob doing it but I think about if I'm not around will she settle down nicely for a sleep? Plus at times I feel like I am constantly getting my boobs out! Just yesterday and today have tried alternative options like trying her with a dummy or giving her a cuddle that way if I'm not there anyone can do those things, sometimes it works othertimes it doesn't it depends on how quickly I get onto het tired signs.
