Asalaamalikum,
Having "too many" kids is relative to each married couple. It all depends on how responsible and wealthy you are. The more kids the better. In fact it is encouraged in Islam to have kids. Inshallah I want have my own army of kids!
Children are the delight of our hearts in their childhood, our companions and comfort in our old age, and the only source of du`aa' in our graves; all in all, they are the means by which we earn the fruits of this life and the reward of the hereafter.
Muslims have responsibilities towards their children, and they stand accountable for these responsibilities so that they can truly enjoy and appreciate the blessings of having children and get rewarded by the Giver.The adult of today was the child of yesterday, and the child of today is the adult of tomorrow. In order for children to fulfill their responsibilities towards their parents, they must first get their rights from them.
Muslim parents should teach their children all about Islam and show them how to worship Allah, with no compulsion or force.They should also guide them to the stairways to Paradise, and protect them from falling into Hellfire. It is the responsibility of parents to provide their children with the environment and tools to learn all about Islam.Upon their birth, children have all of their rights automatically in effect: feeding, clothing, health care, even the celebration of birth (`aqeeqah), Allah says in the Qur'an what means:
[Mothers should feed their children for two whole years (that is) for those who wish to complete the suckling term, the cost of their food and clothing on equitable terms is upon the father of the child.] (Al-Baqarah 2:233)
Also, the Prophet (saw) advised us to give each child a name with a good meaning. Motherhood and fatherhood are instincts that Allah has blessed us with, and the love for our children is built into our hearts even before they are born. Prophet Muhammad (saw) instructed us to show our love to our children:
He is not one of us who does not have mercy for children and respect for our seniors. (At-Tirmidhi) It is reported that Al-Aqra' ibn Habis saw Allah's Messenger kissing his grandchild and said to the Prophet, "I have ten children, but I have never kissed any one of them." The Prophet said, "He who does not show mercy (towards his children), no mercy would be shown to him" (Al-Bukhari).
Also, a Bedouin man asked the Prophet, "Do you kiss your sons?" The Prophet replied, "Yes." The Bedouin said, "We do not." The Prophet said to him, "What can I do for you if Allah has removed mercy from your heart?" (Al-Bukhari).
