About This Week Baby
This Week Baby turns the week your baby is on into a short, plain-language read on what is typically happening in their development, and a few fun things to try together. It is a project of Urban Algorithm LLC.
Quick answer
Is This Week Baby written by pediatricians?
No. This Week Baby is written and reviewed by our editorial team, parenting writers, not pediatricians or another clinical practice. We make no medical or diagnostic claims anywhere on this site.
A celebration, not a screening tool
Every week-by-week entry is written to celebrate what many babies are doing around that age, in soft, range-based language, never a promise about your baby specifically. We do not list red flags or run a delay screen anywhere on this site. When a question genuinely calls for "is my baby on track," we say so honestly and point to your pediatrician and the CDC's own milestone checklists rather than pretending a website can answer it.
How we write entries
Each entry in our week-by-week library is sourced from mainstream, widely-cited child-development references and written in our own words, cited by name. No entry is copied from a paid course, book, or another site. Full detail is on our methodology page.
How we make money
This site may carry affiliate links to products we believe are genuinely useful; if it does, the link is disclosed and it never sits inside the free timeline tool's own results. There is no email capture and no paid tier.
