My daughter is 24 and has a 1 year old daughter. She has had trouble with acne for about 12 years, so she wasn't worse after having her baby but it was frustrating for her that she still had so many pimples. She started on clay 2 months ago and is having good results, so you could give that a try. Check out my post about my son who takes clay with excellent results that gives details. One nice thing is that if you are nursing taking clay will not do any harm to the baby, unlike some other remedies.
