BABY DEDICATIONS 

Behold, children are a heritage from the lord, The fruit of the womb is a reward 

God has given parents the responsibility and blessing of raising their children in the ways of the Lord. He entrusts parents to establish a foundation built upon Jesus Christ early in the lives of their children.
In view of this responsibility, baby dedications are actually:
FAMILY DEDICATIONS
To dedicate a child to the Lord is to make a vow to completely submit your child to the will of God and raise that child in the ways of the Lord. The Bible says "It is a snare for a man to devote rashly something as holy, And afterward to reconsider his vows." Proverbs 20:25.  
Christian parents are to do all they can do to “set apart” their child to God until that child can make his or her own choice regarding a relationship with Jesus Christ. By dedicating a child to the Lord, parents make a vow to raise their child in God’s ways and not their own. They commit themselves to this promise and must do all they can do to keep it.

The responsibilities God has entrusted to Christian parents include continuously praying for their children Job 1:5, instructing them in the way of the Lord Proverbs 22:6, setting a godly example Proverbs 20:7, and disciplining them as the Lord would discipline us Proverbs 13:24. These responsibilities can only be fulfilled in Christ’s strength Philippians 4:13.
