You are not incorrect, happiest.
I’ve even heard this said in front of their poor kids. Which kid wants to hear they are so unwanted that they hear their parent count down the hours till they’re gone?
Oy.
However, I see this as VASTLY different from mothers who may wish to be in the correct mold and feel all fulfilled while at home with young kids, yet they cannot.
In days of yore when there was extended family around, the young mom had support, adult conversation, and physical help.
Loneliness and isolation can be precursors to worse things ahead. Professionals have studied depression among young moms, a condition which hinders the bonding process.
If you fit this scenario, forget the mold and do what’s best for you and your baby without any guilt of not having “true Torah values” or a victim of “brainwashing.”
If this is not you, then perhaps get together with your friends who are raising young kids themselves for adult stimulation and support.
