What the research says · Last updated 7 September 2026
What we read before we built this.
The homepage says When Baby’s Home is grounded in fourth-trimester research. That is a claim, so here is the reading behind it: what the studies found, what we changed because of them, and what they do not prove.
- Offers fadeHelp that is expected but never planned tends to thin out by month three.
- Tasks are their own thingHelp around the house is measured separately from company or a big network.
- Nobody has studied usNo study tested When Baby’s Home. This is reading, not proof.
Why this page exists
“Grounded in research” is doing a lot of work on a homepage. We are not researchers. We are two people who read a lot before building something, and we think you should be able to check our reading. Every study below is linked, with its size and its limits next to it, and the last section is about what none of this proves.
Help is expected more than it is planned
The clearest pattern in the reading is not a shortage of willing people. It is that willingness rarely gets turned into a task and a time.
One study interviewed 22 women about a month after birth and again at three months. Practical help mostly meant food and things around the house. Most of it was assumed rather than arranged, and by the second interview some of the women said it had thinned out. [C01]
A set of focus groups with 33 mothers, six to twelve months on, found the same shape. Real practical needs, an expectation that partners and family would step in, and a list of reasons not to ask. Some of the mothers made lists. Some asked a partner to run interference on help they did not want. [C02]
What we take from it: the hard part is not finding help. It is being the one who has to turn “let us know” into “Tuesday at six,” usually while holding a newborn.
Household help is its own kind of help
A measurement study across three US cohorts of mothers found that help around the house and help with children are distinct things, and both are distinct from how many people you know or how close you feel to them. [C03] A big group chat is not a plan, and a loving family an hour away is not a meal on Tuesday.
A 2024 study of 18 low-income mothers in Texas found that time, care demands and thin support made cooking hard, and that people valued practical help most when they had a say in the food. [C05] That last part matters. Food someone did not choose is a chore to receive.
Distance changes the shape of help, not whether it exists
In a 2021 Pew survey of US adults, 55% lived within an hour of at least some extended family, and 20% lived near none. [R02] That is general adults, not new parents, so treat it as background. Either way, a lot of the people who love a new baby will not be at the door. That is why sending a meal and checking in by video sit beside bringing a meal in the plan, not beneath it.
The people who do this for a living already plan it
A postpartum-plan template from the 4th Trimester Project asks families to think ahead about visitors, meals, errands, child and pet care, supplies, and how they want people to reach them. [D01] A childbirth-educator curriculum asks families what resources they will need after the birth and builds a postpartum plan from the answers. [D02]
Postpartum doulas offer professional, non-clinical support in the home. [D03] We are not that, and we are not trying to be. When Baby’s Home is for the friends-and-family layer, and it works best alongside a doula or a clinician, never instead of one.
None of this is medical advice. If something feels wrong after a birth, physically or emotionally, call your care provider. The plan can wait.
What we changed because of it
Friends raise a hand before there is a date
The offers arrive before the baby does and the dates arrive after. So a helper says what kind of help they would like to give, and real dates open only when the family says the baby is home.
Drop-off or visit is the family’s call
The family writes the instruction once, like “leave it at the door, we’re resting,” and every helper who signs up sees it. Nobody has to ask.
Help from afar is on the plan
Sending dinner and checking in by video are listed beside the nearby help, because a lot of a family’s people are not nearby.
Some friends are just on call
A friend who wants to be reachable for any little thing can say so and leave a number. Nothing is scheduled for them.
The plan runs as long as the family says
Month three is where the support in the reading thinned out, so a plan is not fixed at four weeks. A family chooses a length up to a year and can add weeks after the baby is home.
Nothing is public
One private link, no directory, no lookup. The family decides who holds it.
What this research does not prove
The samples are small: 22, 33 and 18 people. Some of the studies are more than a decade old. None of them is specifically about first-time parents, and none of them tested a planner like this one, or any software at all. Where a study connects support to how a mother felt, that is their finding about their participants, not evidence that our product changes how anyone feels.
We have not run a study of our own. We are talking with families in our beta, and when we have something worth sharing it will go here, with the same caveats. If you know a study we should read, we would genuinely like to hear about it.

Cornish and Dobie, Journal of Perinatal Education, 2018
22 women, interviewed at about one month and again at three months. Small and self-selected, so it shows how support worked for them, not how often it fails in general.

Negron and colleagues, Maternal and Child Health Journal, 2013

Bevans and colleagues, Maternal and Child Health Journal, 2013
