I totally symphasise with you and you are not being unreasonable.
I think parenting these days, especially mothers,are put under a lot of pressure. If they do not work, then there is a lot of pressure to take care of the kids and live up to the standards of 'other mums', their own mums and mother in laws.
For Mums like me, who work and get a lot of help from my Mum (looks after daughter Mon-Wed) and In Laws (Thursday and Friday), there is the pressure of work, commuting, keeping both Inlaws and Mum happy, keeping the boss happy (staying late to finish the work), keeping the husband happy (by not working too late)and housework.
My MIL and Mum also comes up with very hurtful and unsensitive comments and in my Mum case in front of friends and family. Criticising how I'm such a useless Mum/daughter/wife.
I bring money home to pay the mortgage, and help out my Mum financially (although it is not a huge sum), I do the rent accounts, cooking, shopping, housework, etc. I worked my BUTT off to get where I am career wise. I HAVE TO work to pay the mortgage. I don't have a choice. I don't think I am useless. But I am constantly made to feel SO useless by my MIL and Mum. AND it is the same comments; 'you can't cope with one, how you are going to cope with another one....I raised three kids...., if I had as much help as you have I'll be able to fly..etc....'. WHY WHY WHY????
I get a lot of S@? at work, come home and s@? as well. Why can't the older generations give us a break???? Yes, I do get a lot of support and help, but it doesn't mean that there is no pressure, no stress, no worries. With the help, comes the guilt of not being able to stay at home and be with your child, the guilt on relying on someone else to look after your kids, the pressure of being able to pay the mortgage.
No wonder there is an increase of depression amongs our generation. If it wasn't for Mumsnet, we all wouldn't have a 'voice' or 'space' to vent our anger and opinions. So in a way we are lucky, but no excuses for hurtfull and insensitive comments from the older generations.
