to tell my sister that she will miss out on many of the most important milestones in her baby's life if she sends her aged six months to nursery 5 days a week from 8am until 6pm. This is longer than a school day. My sister got very offended when I suggested that being looked after as part of a cohort of 8 babies by three carers was not ideal for her seven month old daughter. She doesn't need to work full time but loves her job and is worried that if she goes pt she'll miss out on promotion. Is it unreasonable to think that now she's a mum she should put her daughter's needs first?
