I do not regret my purchase, just not to have done before. I was so sick that my daughter bumps, if only once a day as unbalanced and fell backward or forward from a sitting position. I had this personal remark that turned me ds the head: the head is weak must be protected, the child needs his head life. It's like letting a child play on the 1st floor without barrier. I can not find the baby learns àqu'il should not fall because it hurts, by dint of falling. No it is not reserved for Americans.
