Yes ds1 goes to nursery 4 days per week and has done since 11.5mo.
He was the most fussy baby ever during his first year!! Not necessarily clingy to me: just cried all the time, massively frustrated at every stage of development etc.
He took about 3-4 weeks to properly settle into nursery- cried a little a drop off every day to start with.
He settled into the daily routine there really quickly though. Like lots of fussy babies I think he thrives on routine, so knowing what was going to happen at the same time every day really helped him I think.
Nowadays (16mo) he LOVES nursery and is to all intents and purposes a dream child there! Be prepared: your fussy baby may be much less intense for another carer! This came as a shock to me.
Ultimately DS has always needed lots of stimulation and nursery is a non stop fun-factory so he is happy there. I noticed an almost overnight improvement in his mood/less grumpy grizzling when he started btw. I think he was finally getting enough stimulation out of the day.
Good luck, you and she will be fine!
Oh and if you've spent a year looking after a high needs fussy baby this is the best bit: the peace and quiet and freedom of returning to work. Bliss!!
