Choosing the right school

I am happy today. We are heading for a short family break at a resort just a few minutes away from home. We just want to bring Sona to have fun in the pool and to spend time at the beach. As for me, I just need some time away from home. Since we have a new addition, Sona changed in her behaviour. She behaves like a baby   all over again. She wants more attention, nurse more than four times a day and wants to get me involves in everything she does. At first I was worried, but after some readings and information from friends, I found out that the behaviour is normal. She feels insecure seeing her mum spend more time with the new baby than her.She need some distraction.  Therefore we have been thinking of sending her to school. She needs to fill up her time doing something and going to school may gives her more activities to do not forgetting she will have new friends as well. The journey of finding the right place to send her should begins soon. I have been to a boarding school since I was twelve and sending a child to her first school marks an important journey in her life. We have been talking to her about the idea so that she will not feel that we are sending her away because we dont love her. Kids can be very sensitive with certain issue. She even wants me to follow her to school. I just hope we'll find a good school for her and she will enjoy it. I may start to look at few places nearby and doing some research of those places. Mummies out there, and advice to share?
