Where to take an infant's pulse

[gfoster6993]

I am a first year student. Can someone please tell me the best place to take an infant's pulse? Is it the brachial or apical? Also, at what age can you take a child's radial pulse? We were asked this question in class, and I just assumed you could take a child's radial pulse at any age. Any comments will be appreciated. Thanks

Apical. Brachial for BLS/PALS standards.
