'Aqiqa for boys and girls

'Aqiqa is to sacrifice an animal on the occasion of birth. These are 2 hadiths about it:

I heard Allah's Apostle saying, "'Aqiqa is to be offered for a (newly born) boy, so slaughter (an animal) for him, and relieve him of his suffering."

The majority of Muslim scholars agreed to the Hadith reported in Sahih At-Tirmidhi that the Prophet (s.a.w.) ordered two sheep for a male child. This is considered a sunna:

Narrated ‘Aisah (r.a.): Allah’s Messenger (s.a.w.) ordered them that two equal sheep are to be slaughtered for a boy, and one for a girl (at their birth). (Reported by At-Tirmidhi)


I know that there is a verse in the Quran that condemns those who show dissatisfaction when a baby girl is born but why should we sacrifice 2 sheep if the baby is a boy and only one if the baby is female?
It's like the birth of a boy is more appreciated than the birth of a girl
