No idea why they’re in a rush to send him to nursery. My brother has a baby similar age and the difference is insane. They never go out to play groups, I swear he’s always in the house watching tv.
Babies thrive seeing other kids even with their parent and having worked in a nursery I’d never send my baby to one.
The stuff you can do as a parent / grandparent with the child will give them so much more, but that’s if she actually took her baby out to somewhere other than a soft play. What about messy play clubs, sensory class, music group, baby gym. The options are endless..
