Why we built these
Every tool here exists because we needed it ourselves. The wake windows calculator solved 4-month-regression sleep math we were doing on the back of envelopes. The feeding calculator translates the "2.5 oz per pound" pediatric rule into something you can actually use at 3 AM.
All tools are free, work on phones, don't require accounts, and don't sell your data. They're built from the same pediatric guidelines pediatricians use. We just made them faster to use.
