Here are some pros and cons of water births.

I would definitely opt for water births as it reduces stress and the pain. But I guess it is not recommended for all. My sister who is 6 months pregnant would like to have a water birth but she is not sure whether she is the right candidate. She had undergone a breast augmentation procedure in Barrie about 2 years ago. She is worried whether it is recommended for those who had undergone such surgeries. She has booked an appointment with her surgeon to clarify her doubt.

Thanks for sharing it.

My son is18 months old and started walking.  But his legs has a bend. First I thought that it is normal. But my brother who is a medical student informed me that it could be bow legs. I am worried. He recommended a pediatric chiropractor in Oakville ( http://www.oakvillechiropractic.com/services/chiropractic/children-chiropractic/ ). But will this treatment be effective for bow legs? Or should I take my child elsewhere? Please suggest.

Even doctors are not sure what is the root cause of pregnancy sickness. It could be the body's reaction to the pregnancy hormones and it is produced in higher levels during the first trimester. And that could be the reason why the sickness is experienced during the first trimester.  Also during pregnancy, the sense of smell is higher, which could stimulate nausea.
