@ZooKeeper19 sorry but why do you get to say what is or is not ideal for someone else's child? My DC has been at nursery full time since 8 months. It is ideal for them, for me and for DH. I don't need to justify to you why it's ideal but in case you're interested:
It's ideal for us because: we need to work, for financial reasons yes but also for mental health reasons (I would go crazy if not working), for career reasons, etc.
There is no alternative that would allow us to work. I wouldn't have family look after DC - they too are working, are mainly based abroad, and to be honest I don't think they would do as good a job as a trained professional.
The nursery is extremely close to home, very well respected, clean and friendly.
It's ideal for DC because: they have been so restricted during the pandemic. This is the only time they get to see a face other than mine or DH's without a mask. They have NEVER seen another face close up. Yes, they would get that benefit with part-time nursery too but it's a huge benefit to have and I would like to expose them to as many faces as possible. While at nursery they are: fed well (it's all organic, home-cooked food, etc.), they can play with toys that I don't have, there are activities available that I can't offer, there are other children to play with or alongside.
In the morning, the evening and at weekends, we are able to devote all of our time and attention to DC. There are no distractions of laundry, chores, etc. Our sole focus is them.
If DC were home some of the time, there would be: financial strain, a frazzled mum, increased tension between me and DH trying to juggle everything, fewer activities, no children to play with, a distracted mum trying to keep all the plates spinning.
Now which one sounds more ideal....?
I'm not saying that full time nursery is right for everybody. It's totally dependent on the child and the parents. But to say it is not ideal for everyone is incorrect.
