Don't slip into the mental load.
I did, 32 2 kids, busy busy running a business, juggling kids, having fun, social life was great.
It took until I was 39 to sit back and notice I was now weirdly in charge of the food shopping, the cooking, the cleaning, the Christmas gifts, arranging social lives, booking holidays.
I was so capable and strong and focused I just lost myself. And by the time I realised my DH was having a great time all at my expense.
So I flirted with other men to get attention, had an affair to get attention my self esteem was on the floor by this point.
It took the above to flip around and for my DH to realise I'd spent my 30s serving the family while also being the breadwinner.
So my advice be mindful of how capable you appear to be, take sundays in bed, don't take everything on and drift into a role that I did.
Oh and also learn what peri menopause is, I only found out when I was 40 that it's a thing.
The pensions, keep healthy advice is all great.
