hi and congrats on your new baby, when i first got a second baby my bailie ignored her for a while , i never MADE them be friends i just let nature take its course and they bonded really well, then i added a third and my wee female licked and licked the 3rd baby, they are inseperable, then a 4th lol and now they all great together, to me its a good thing he is cleaning her, and its amazing how one learns from the other
