I think there is a lot of anxiety around this where if I am honest 6 years on with my eldest I realise it's not as do or die as it feels when they are newborns.
I have for various reasons had different periods, sometimes they have had to be in full time childcare as I worked long hours to keep a roof over their head and sometimes they have been at home.
What I genuinely realised is as long as you keep up the attention and support at home it honestly doesn't devastate them long term. I found it harder , the mum guilt was enormous.
When the DC were babies I had to work full time to keep the wolf from the door and now I am grateful that I inadvertently kept my career going, ironically it meant those hard years got me senior enough I can now work school hours mostly. Had I not gone back to work I would still need to jump to my employers tune.
They flourished in nursery and loved it , it did wonders for their social skills.
Saying all of that , it was very hard, a sickness bug was horrific when they were off for 48 hours , full time work meant we were scrambling to get time off (and when they first went it seemed bloody constant), many a time when dashing from a meeting to get to the nursery before pick up time I wished I could stay at home.
I guess what I'm saying is there are downsides to both options, but despite some fairly awful people asking me why I bothered having children if I stuck them into nursery full time we have come , more or less , out the other side. Ds2 is in his last year of nursery but it's in his brothers school, for me now it seems more important to be around than when they were babies .
As babies they had less concept of mum working but now it matters to them that I can pick them up from school and we walk home and talk about their day.
What I do remember is the comments form others and the opinions everyone and their dog seemed to have. I now realise they weren't worth a damn, i did what i had to do, i tried ( sometimes failed) to make the best decision i could at the time and honestly we survived, and did well. Make your decision that feels right, i learnt ignoring my own instincts generally turned out to be a bad idea.
Also the money does help, people who say it takes away from your time with your child have usually never experienced the stress of a failed mot and no money to fix it, the stress takes you away anyway really.
The peace of mind that we weren't struggling I honestly feel made me a better calmer mum
Sorry not a definite answer just my experience , it's a double edged sword but you can only do what works for you
