It is sexism though SandyY2K because even in that post you are valuing paid work outside of the home over the contributions of the parent who stays at home. And in the majority of cases, that is the mother.
What I'm saying is that in your specific situation...if it was your DH that stayed home the responses would be the same.
As far as valuing paid work more...paid work is essential to have a decent lifestyle...so it is important.
For me...I stayed at home only for maternity leave (worked part-time). I'm not in favour of being a forever SAHP..... I didnt study to postgraduate level to give up my career because I had children. I preferred to contribute financially and maintain financial independence. I've seen far too many women trapped and suffering as SAHMs.
Having said that I wouldn't ever underestimate what's involved in looking after a baby. I've been through it twice.
Babies/toddlers need that early nurturing and one of my DCs was a little like your DS as a baby. Very clingy..wanted to see me as long as she was awake.
If I went to the loo she would cry...so I had to carry the baby bouncer upstairs and leave the bathroom door open. I hated the crying so she went everywhere with me ... in every room. I just made it clear to DH it was not possible to do much around the house in the day as baby cried if I left her.
I'm sure it's much harder with an adopted child too....as the bond wasn't developed during pregnancy.
It's just 4 months in...so be firm on it from now or it almost becomes irreversible.
When I didn't get the assistance I felt was needed I made sure it affected DH..so he could feel the impact.
Whether that meant I wasn't going to cook, or didnt go to visit his parents with him (and he didn't want to go without me) or I was too tired for sex...he had to feel the impact or nothing would have changed. When a situation doesn't affect you..there's a little motivation to change.
Start making it affect him.
