With DD1 who was a July baby, I had to remove them at about 7mos. With DD2 who was a Dec baby I was able to wear them the entire time. So, summer, IMO, definitely has a negative impact.
Mom to two amazing DDs ('07 & '09) and a fur baby.
Gluten free since Nov '11 after non-celiac gluten sensitive diagnosis. Have had great improvement or total elimination of: migraines, bloating/distention, heartburn, cystic acne, canker sores, bleeding gums, eczema on elbows, dry skin and scalp, muscle cramps, PMS, hair loss, heart palpitations, fatigue. I'm amazed.
