beanieb, you really don't want to trouble yourself with happyhoney's opinions.
You can plan to return to work as you intend. I did too. Then my dd was born with health problems and a clingy high maintenance one at that. I changed my plans and postponed my return from maternity leave from 6 months to 1 year and got my mother to live with us (huge compromise particularly from my dh's point of view) to ease her very slowly into nursery, fully intending to pull her out if she did not settle. To my surprise, she did . I went through a lot of hoops to get my company to give me flex working, despite my original plan to go back ft.
Even though I thought I would hate work and miss her (hormones, brain washing?), I actually did not because I felt she was happy at nursery. I have never looked back since. Work is now a source of fulfillment and stimulation in addition to the joy of my family.
My advice is if you know you want to go back to work, just execute it. If you feel childcare is not working, change it. If it is still not working, tweak your work arrangements. You will eventually find a solution that works for you, dh and dcs. Don't be put off by silly remarks like this OP or so-called research. If you treat your dcs as the barometer of whether something is working with them, they will be alright .
It is alright to plan and accept that you don't have all the answers until you cross the bridge. Hope to welcome you to the club soon.
