Present Perfect or Past Tense correct?

[Anneliese]

I'm actually not sure which version is correct: Do you say "The baby has cried four times today" (the day isn´t actually finished and it could keep on crying) or "The baby cried four times today" (a situation in the past). There are two different meanings of teachers. Could you help me, please?

Both are grammatical, but the former is more common in BrE.
