Try reading this as an invocation before praying over your child with laying on of hands 

Heavenly Father,

Thank You for loving this child even more than I do.

Thank You for being present with us by the power of Your Spirit.

Thank You for wrapping her in Your loving arms through this prayer from my heart.

Please pour an abundance of Your healing graces

into every precious cell of her body, while she rests.

From the crown of her head to the tips of her toes,

fill her with Your pure spirit of love.

Clear away any source of illness or distress,

and replace it with Your peace and a sense of the abundant life You have for her.

Comfort her emotionally, and restore her physically.

Help her to experience Your presence through this time of prayer,

so she realizes You will always be there for her, when she needs You most.

In Jesus name we pray, 

Amen
