Stop making excuses for your children. 3 years old is too old to be drinking from a bottle. If they want milk----put it in a sippy cup or a plain cup and drink it and then send them off too bed. I can understand about the skin condition and the potty training should be just about completed but the bottle is a big NONO in anybody's book. It will ruin their teeth and also cause dental problems leading up too braces when they get older. Braces are not cheap--been there--done that.
