20 kg is the mass of the child, not the weight.
Weight is calculated by multiplying the mass and acceleration due to gravity.
On the surface of the Earth, that is about 10 m/s^2
So 10(20)= 200 Newtons, the approximate weight of the child.
For a more exact number, use 9.81 as the accel. due to gravity.

Well the conversion of kg to lbs is 1 kg = 2.2 lb so that means that here on earth a 20 kg object would weigh right around 44 lbs.

20 Kg. The earth gravity is the benchmark used.

Weight is actually a force. Kilograms is mass, not weight. To get weight, multiply mass times acceleration.
Weight = mass x acceleration = 20 kg x 9.8 m/s/s = 196 Newtons.
