We should keep the following hadiths in mind when dealing with our children:

Abu Huraira Radi Allahu anhu reported that al-Aqra’ bin Habis saw Allah’s Apostle (may peace be upon him) kissing Hasan Radi Allahu anhu. He said: I have ten children, but I have never kissed any one of them, whereupon Allah’s Messenger (may peace be upon him) said: He who does not show mercy (towards his children), no mercy would be shown to him.
Muslim :: Book 30 : Hadith 5736

The Prophet (peace be upon him) said, “He is not of us who does not have mercy on young children, nor honor the elderly”
(At-Tirmidhi)

The Prophet (peace be upon him) said: Act equally between your children; Act equally between your sons.
Sunan of Abu-Dawood Hadith 3537,Narrated by An-Nu’man ibn Bashir

‘A’isha (Allah be pleased with her) reported that there came a few desert Arabs to Allah’s Messenger (may peace be upon him) and said: Do you kiss your children? He said: Yes. Thereupon they said: By Allah but we do not kiss our children. Thereupon Allah’s Messenger (may peace be upon him) said: Then what can I do if Allah has deprived you of mercy? Ibn Numair said: ( has deprived) your heart of mercy.
Muslim :: Book 30 : Hadith 5735

The Apostle of Allah (peace be upon him) came to some children who were playing: He greeted them lovingly.
Sunan of Abu-Dawood Hadith 5183,Narrated by Anas ibn Malik

Al-Bara’ said, “I saw the Prophet, may Allah bless him and grant him peace, when al-Hasan Radi Allahu anhu was on his shoulder. He was saying, ‘O Allah, I love him, so love him.'”

I prayed along with Allah’s Messenger (peace be upon him) the first prayer. He then went to his family and I also went along with him when he met some children (on the way). He began to pat the cheeks of each one of them. He also patted my cheek and I experienced a coolness or a fragrance of his hand as if it had been brought out from the scent bag of a perfumer.
