Short, evidence-informed action plans for specific toddler behaviours (biting, hitting, tantrums) with a daily check-in tracker.
The problem people are complaining about
On 2026-10-21, a thread titled “My son won't stop biting and I'm about to lose my mind” reached #16 in our daily ranking of parenting problems on Reddit. In parenting, people most often struggle with behaviour, sleep, school, screen time and co-parenting challenges; this one stands out because the person asking has a concrete, repeatable need rather than a one-off emergency. When the same question keeps appearing in public, it usually means existing products either don't reach these people or don't answer the question in the way they need. That gap is what Toddler Behavior Coach aims at.
Who the customer is
Parents of one- to four-year-olds dealing with biting, hitting or tantrums, often stressed because daycare has warned them.
In short, the first customer to target is: Exhausted parents of 1-4 year olds. Start with the narrowest version of this group you can reach directly, ideally in the same communities where the problem was posted, rather than trying to serve everyone with the problem at once.
The idea
Toddler Behavior Coach is a subscription app idea. Short, evidence-informed action plans for specific toddler behaviours (biting, hitting, tantrums) with a daily check-in tracker. It makes money through $6/mo or $39/yr; partnerships with daycares.

Pricing guess
Estimate: $6/month or $39/year; daycare partnerships later. This is our estimate, not market data: treat it as a starting hypothesis and test it with real buyers before relying on it. Price anchors from the alternatives below and what people already spend on workarounds are the best reality check.
MVP you can build
Month: 10 behaviour plans + SMS/email check-ins. Keep the first version deliberately small: the goal is to learn whether people use it and pay, not to build every feature.
How to validate it in three steps
- Publish one free biting action plan and measure email signups.
- Partner with a child psychologist or pediatric nurse for credibility.
- Offer a paid 14-day check-in programme to the email list.
Decide your success threshold before you start each step (for example, a number of signups or pre-orders), so the result actually tells you something.
Competition & existing alternatives
Big Little Feelings, parenting books, pediatrician advice Before building, try each alternative as a customer would and note exactly where it fails the people in the threads; that gap is your positioning.
Risks
- Parenting advice is crowded.
- Needs expert backing to be trusted.
- Parents churn as children grow out of the phase.
How we scored it
Opportunity score (6/10) is an editorial judgement combining four factors: how strong and frequent the demand looks, whether the customer already spends money on the problem, how crowded the alternatives are, and how much effort the first version takes. Signal score (3/10) is calculated from our data only: 2 points for one thread, 4 for two, 6 for three or more; +1 for each extra day the problem appears (max +2); and +2 if it ranked in the daily top 10, +1 for top 25, +0.5 for top 50. Neither score is a forecast. See how it works.
