I think u need to provide the mass of the child

The normal reaction force is mg cos29.
The frictional force is 0.4 x mg cos 29 = 0.35 mg.
This force is opposing the component force mg sin 29 =0.49 mg
Net force on the baby is mg (0.49 - 0.35 ) = 0.14 mg.
Acceleration is force/ mass = 014 mg / m = 0.14 g = 1.37 m/s^2.

well. The formula for this is F=M/A, so it is impossible if mass is not given.
