I always thought I'd work in a private nursery but when I went on placements in different settings I loved the TA role. Could she volunteer in a local primary school to see if she likes it?
Some primary schools do still have the nursery nurse role but they have been phased out recently in my area unfortunately (they were on a different pay scale to TA's and earing more so council wanted rid and now TA's do it!)
If I'm being honest both jobs are not the best paid but many childcare workers do it for the love of the job not the pay. Its very rewarding.
Nursery hours are long and usually minimum wage. There is a lot of paper work to do in the role of being a key worker. There is a chance to become a room leader though and work way up.
TA hours are usually 8.30 - 3.20 (every school is different) the job role is becoming more demanding and quite often TA's will be left with a class to do PPA not every school does this but its happened to me many times in the past and I just didn't think it was fair as I'm not a qualified teacher. Thankfully the school I work in now has HLTAs who cover lessons when needed.
One thing to beware of is the way TA jobs are advertised it will say £18k - £20k but that's based on full time hours when in reality you get paid for 39 weeks of the year spread out each month. So roughly I get around £10k a year.
I prefer working with foundation stage children and not a big fan of working with toddlers.
There are many schools that have a nursery attached on so if your daughter wants to work with younger children this could be an option.
Benefits about working in a school is that your paid by the council so get quite good benefits for example sick pay, years of service etc...
Ive done both jobs and I'm much happier being a TA plus its lovely to get the half terms off 
TA wage for me - £850 a month doing 28 hours a week
Nursery nurse wage for me - £1050 a month doing 40 plus hours a week
I'm based in the North West area.
Good luck it's a great rewarding job to do x
