When should one name their muslim child (baby)?

Allah's Messenger (S.A.W) said that: "Every child is held in pledge for his Aqeeqah which is sacrificed for him on his seventh day, and he is named on it and his head is shaved." ('Saheeh' by Shaikh al-Albanee '1165' Abu Dawood 'vol: 2, no: 2831' and as well others)

Another narration in this aspect is related by Anas (R.A), who said: 'Allah's Messenger (S.A.W) said: "A boy was born to me this night and I have given him the name of my forefather Ibrahim." [Saheeh Muslim (4/ 5733)]

So what these Ahaadeeth is saying, that the child can receive a name on the first day of his birth or it can be put-off until the seventh day reaches. However, what is recommended is to give the name to the child on the seventh day, as such is related in the saying of Allah's Messenger r. Now regarding the Hadeeth which has mentioned that the Prophet's practice is taken as an evidence to prove that the child can be allowed to be named before the seventh day.
