I'm not a parent but aren't toys and play time super crucial for a baby's development?
Yep it's a huge part of helping babies and children make sense of the world around them, helping them to re-enact situations around them and assist to them to use their imagination, process new information and scenarios in their life. It also assists a child with socialising and sharing with their peers.
Now Melanie might think that giving a child pots and pans and a chopping board is enough to spark an imagination but it's not.
Dolls and house for example help a child act out those roles - the responsibility of taking care of a home, dolls and babies - help a child learn empathy by caring for and nurturing them, they then go on to bring these learned behaviours into the real world with real people.
Even language and play time are a huge factor in children's development as they socialize more during play time with peers, their scenarios and stories become more complex and imaginative. Toys are also a huge part in helping children discuss/have an outlet with traumatic or fearful experiences.
Simply put children need more than pots and chopping boards for stimulation. A child cannot make sense/re-enact parental figures and the roles within society via a chopping board.
Melanie's really going for- "my baby is not like other babies, he doesn't need toys, he's imaginative all on his own" which is not the attitude to have and will cause an impact if she doesn't buck up.
