My mum worked. I had a combination of nice nannies and nursery.
I don't remember ever feeling like I was missing out on time with mum. I had nice day care, and had good times with my mum at weekends and the evenings.
Mum was probably a happier person for not having to give up her career a second time.
When I was too old for nannies we did a mixture of mum picking me up from school 2 days after the after school club, dad did one day, my gran did one and I went to a friends on one day.
School holidays were a mix of parental holiday, sports clubs, pgl holidays, stay with my aunt for a week, and a little bit of going to work with mum sometimes. I was quite content to sit and read for hours so quite easy to look after really.
She did take early retirement when I was about 10 which 'luckily' coincided with a time I became quite ill. I'm not sure what it would have been like if she had been in full time work while I was in hospital and recovering at home.
She then went back to work part time so while I was early secondary and I do remember it was nice having her at home when I got in usually but I'm sure it would have been fine without.
Honestly I can't remember ever feeling like work got in the way of family life. I knew she loved me, and I basically for the best of both worlds. A happy mum in the evenings and a good nanny/nursery during the day.
