It's a full time job

No matter what people say or how they may jest, looking after baba is a full time job, feeding, changing, settling, changing bedding, washing, sterilising, expressing (if you so choose to do so), immunisation/weighing appointments it all adds up. I for one never realised just how busy a new mum or even Dad can be.
Whilst it is said to be one of the most rewarding jobs you can ever do (& I agree), It can also be a thankless job (although I hear this continues well into the teenage years!)
There is also the pressure that particularly woman put on themselves to be the perfect homemaker as well as a mother. Part of this I think is that often babies have no 'end product' they can't reflect how hard you've worked all day particularly if you've had a mad tidy round at 4.30. My husband is very supportive but he can work long hours and as well as doing all the baby related tasks, I feel I need to tidy the house, cook the Tea, do the shopping and organise any jobs that need doing. He is very supportive and wouldn't I hope, ever say the dreaded 'and what have you been doing all day' but the thought looms ever present.
Why is this? Why the need to be a 'domestic goddess'? I think for many woman myself included it's what our mothers did (& seemingly effortlessly albeit seen through a child's eyes, it was probably anything but.)
Also as a working woman on maternity leave I feel a sense of self - induced pressure to make sure I am as busy in my new job as I am in my 'real' job. This I think links back to my original point that many people think that parenthood is a doddle and that whole 'hardest job in the world' is just a cliche.
 It's funny though as I'm never usually someone who feels I have to justify who I am. The fact my baby is happy, healthy and growing out of their 'new baby' wear at a top rate should be all the feedback I need and I'd tell anyone else the same. Now if only I could convince myself of that...
