I would favour an AMD Ryzen 7000 based laptop. Much better battery life than Intel and better graphics performance.
Lenovo ThinkPad T and P series are excellent build quality.
Asus Zenbooks or Expertbooks with OLED screens are also excellent. Displays are on par, or superior to Macbooks. Excellent colour accuracy.
Make sure you get something with at least 16GB of Ram, or 32GB if available.
It’s also very important to vote carefully before deciding to have a baby. In most 1st world countries, you get a few family responsibilities leave days a year, that an employer cannot deny.
Under law in those countries, you are a parent first and an employee second. That comes with privileges and responsibilities.
