Children

Apparently I don't have a blog posting for searching for info about children

This is useful when the limits ("Adolescent"[Mesh] OR "Child"[Mesh] OR "Infant"[Mesh])
 just aren't doing it for you. Which is kind of often, because of the whole "is 18 years an adolescent or an adult" thing, plus the whole reviews-don't-require-checktags thing.

If you're looking for everything you can find:

child[all fields] OR children[all fields] OR childhood[all fields] OR pediatr*[all fields] OR paediatr*[all fields] OR juvenile*[all fields] OR adolesc*[all fields] OR teen*[all fields] OR youth[all fields] OR boy[all fields] OR boys[all fields] OR girl[all fields] OR girls[all fields] OR infan*[all fields] OR newborn*[all fields] OR neonat*[all fields] OR toddler*[all fields] OR preschool*[all fields] OR pre-school*[all fields] OR school age*[all fields] OR elementary[all fields] OR high school*[all fields] OR secondary school*[all fields] OR grade school*[all fields] OR preteen*[all fields] OR pre-teen*[all fields] OR prepubescen*[all fields] OR pre-pubescen*[all fields] OR middle school*[all fields] OR schoolchild*[all fields]

If you're trying to narrow to just the pediatric-specific stuff:

child*[tiab] OR pediatr*[tiab] OR paediatr*[tiab] OR juvenile*[tiab] OR adolesc*[tiab] OR teen*[tiab] OR youth[tiab] OR boy[tiab] OR boys[tiab] OR girl*[tiab] OR infan*[tiab] OR newborn*[tiab] OR neonat*[tiab] OR toddler*[tiab] OR preschool*[tiab] OR pre-school*[tiab] OR school age*[tiab] OR elementary[tiab] OR high school*[tiab] OR secondary school*[tiab] OR grade school*[tiab] OR preteen*[tiab] OR pre-teen*[tiab] OR prepubescen*[tiab] OR pre-pubescen*[tiab] OR middle school*[tiab] OR schoolchild*[tiab]

For Ovid Medline:
