ROFL - DP and I work in the same industry. He's stayed on track whilst we've had 2 kids. He works all hours in hopes of the big payout, whilst I pick up all the slack with the house and kids.
I'm hugely lucky because I've been able to keep my hand in freelancing, with some good contracts from contacts made before I had kids (thank god I had kids late so could make those contacts). I am excelling. I am earning as much as he does whilst doing 80-90% of house and kids, and it's bloody hard work (only doing it because if things go well we'll be able to retire in the next couple of years). Earlier in my career, and still to a certain extent now, I've missed out on opportunities and contacts because I'm a woman, and therefore my boss didn't want to take me on a sales trip somewhere, or my boss doesn't feel they can go out for dinner and beer with me (and especially not on to whatever else they get up to according to DP). It stings, but some of these contacts I get work through, only feel they can work with me because they also know DP, and know therefore it's safe to work with me, and DP sometimes networks with them almost as my proxy.
So is the ceiling there? No.
Is it still a much harder battle for women? Hell yes.
Is some of that kinda of our own devising? Sorta - I mean, I could tell DP that we're over, that he has the kids 50% of the time - but my contacts would then have to pick sides, the kids would suffer (we were talking about something else, and DS1 casually said "oh, yeah, like when dad's looking after us and he forgets to feed us" as if it was the most normal thing in the world), my life would be no easier, and aside from this general issue, I rather like DP. So perhaps I've made my own bed here a bit - but there was a big spoonful of societal expectations dumped in there.
