So difficult to assemble

The actual walker is of fairly sturdy quality but trying to assemble it is a nightmare!! I have been trying all day to push the front wheel into position and they just won't go. Neither will the brake pads. I am now trying to get the padded seat into position and secure.....my fingers are red and sore with pushing and pulling. I acknowledge parts have to be tight and secure to keep baby safe but this is beyond belief. Think I'll send it back
