is 男児 the same as boyfriend or am i stupid

ok so i saw 男児 on a post and i thought it meant boyfriend because of the male kanji but then my friend said no thats kareshi?? but then i looked at 児 and it looks kinda like 兄 so is it like male brother? or is it just a normal boy? im so lost with these kanji that look like they have little legs at the bottom idk help
