All sunscreen labels list a sun protection factor (SPF). SPF is a measurement of how much protection the sunscreen offers from the UVB rays that cause sunburn. A few sunscreen labels also list a "PA" ranking, which refers to the amount of protection the sunscreen offers from the UVA rays that may cause long-term skin damage. PA rankings are listed as PA+, PA++ or PA+++. The more +'s, the more protection from UVA rays. For maximum protection from both UVA and UVB rays, choose a broad-spectrum sunscreen that contains avobenzone, oxybenzone, mexoryl, zinc oxide or titanium dioxide. Apply sunscreen liberally 30 minutes before going outdoors and reapply every two hours.

P & E 可以做起来了，很容易。他们都是先慢慢跪着，然后重心后移，腿就立马变成座的姿势了。真有意思！
E 很神气的总是喜欢自己站起来，只要一放下，立马的把着小床的栏杆或者是栅栏慢慢移动的走，真快啊，自己还可以从栅栏换到travel Crib那边。真是show off ! :-)
上周吃了peanut butter， 感觉你们很喜欢。还尝试了很多新的蔬菜，例如：zuccini, asparagus and cauliflower.
对了，还有上周的story time，遇到了另一对女twins，好可爱，他们4个人玩在一起。P 去抓女孩子的耳朵， 呵呵。好玩。
我自己呢，学习了怎么选择sunscreen.
