Maya creates too many long thin triangular faces which makes the meshing slow down. Do some SpaceClaim tutorials on this site and learn SC. Either build the car seat and baby from scratch in SC or learn how to replace Maya's collection of faces that represent one smooth face with one smooth face in SC.
Many of the parts of a car seat are thin-walled parts. For those parts, you want a surface, not a solid body. For example, below is the back face (approx) of the chair part which could represent the midsurface of a thin-walled part that is the hard-plastic molded shape of the chair. You can easily mesh this in mechanical and assign the thickness to that surface.
Here I have used the Merge Faces tool on the Repair tab of SC to combine a row of triangles into a single face.
The seat back above was made by copying those faces off the back of your model.
I have modify the faces and the back seat. I'm currently gathering the properties of the all bodies (material etc.), I've success done the meshing and it's about 130k elements. What I gonna do next is applying material properties, applying profiles and boundary condition.

Hi Peter, I don't know why can't add post through that so I screenshot.
Looks good. This site interprets the text typed in the post as code so it can render special characters, but if some code is found and it's not valid, then you can't post.
I can't post my reply.
The error i always have
I found the way to change the maximum core, but when I change to 4, it appeared error. 572199 equations by the way.

Did you follow the advice in the error to turn on Identify Element Violations on the Solution Information folder?
Show an image of the elements that are becoming highly distorted.
Yes I had the same problem as the last image you posted. The element which highly distorted I have create a name selection but the error still occur.
Okay, so reply with the image of where the highly distorted element is,
Change the thin parts, like the straps, from solid to sheet body and mesh with shell elements. You have to set the geometry to Mixed Import Resolution: Surfaces and Solids.
Bodies with one element through the thickness image. Currently running with identity element violation on with 10. Will share the result soon.
Since there are only a few small bodies with one element through the thickness, use Mesh Controls to force them to have at least two elements in each direction.
I expect there are a lot of elements to fill the solid volume of the baby. Since this is just an approximate representation of the baby, in SpaceClaim, you could copy all the surfaces from the baby and paste them in, then delete the solid. The surfaces will be meshed with shell elements that get assigned a thickness. This will greatly reduce the number of equations the solver has to solve at each time step, reducing your wait time.
