Dont feel bad! I think its good that you take some time out, its good for you to have time away from the baby, especially when they are small and not giving you much sleep, its normal and healthy, plus letting your child get used to other people caring for them will mean they are less whiney and dependent on mummy all the time, and should be better behaved for other poepole when you want to go out in the future. There is nothing wrong with taking time out and letting other people help out.
