Kate’s damned if she does and damned if she doesn’t. The late HMTQ was/has been massively criticised for not spending enough time with her children when they were young. Kate is more hands-on, but apparently that means she is lazy?
Also, being a working royal is a life long “career”. The Queen was still working aged 96, no retiring aged 67. If you’re going to do that, there’s no way you’re going to be working the British average of 37 hours per week.
