SizeSeason: Baby Clothes Size

Predict your baby's clothing size by season and make smart second-hand or thrift store purchases!

Every parent has faced this issue: buying a beautiful winter coat or a cute summer romper in advance, only to realize when the time comes that the clothes are already too small or way too big. Babies grow at an incredibly fast pace, and matching their growth curve with changing seasons is a constant challenge.

That’s where SizeSeason comes in.

SizeSeason is the first intelligent assistant that crosses pediatric growth curves with local climate data to accurately project your child's ideal clothing size for every month of the coming year. Whether you shop on second-hand apps (Vinted, eBay, Facebook Marketplace), at garage sales, thrift stores, or clearance events, you will know exactly what size to buy in advance.

▸ KEY FEATURES

• Seasonal Size Timeline (ForecastView): Browse a complete 12-month calendar. For each future month, the app estimates your baby's age, the average regional temperature (based on 150 offline climate profiles), and the recommended clothing size (supporting US and EU/cm standards).
• Tailored Growth Engine: The app integrates official WHO (World Health Organization) growth percentile curves. When you input your baby's height and weight, the algorithm automatically adjusts to their actual growth percentile (e.g., 75th percentile) for highly accurate size projections. It also manages gestational age correction for premature babies.
• Simple Wardrobe Tracker (WardrobeView): Easily log the number of clothes you own by category (light tops, warm tops, bottoms, coats, sleepwear) for each standard size (from newborn to 3 years).
• Gap Detector & Smart Shopping Checklist: The app compares your baby's actual wardrobe inventory with future seasonal size predictions. It automatically generates a checklist of missing essentials (e.g., "Needed for this winter in size 12-18m: 2 warm coats and 4 footed pajamas").
• PDF Export for Thrifting: Generate and export a clean, minimal shopping sheet listing your needs by size. Perfect for printing or checking on your phone while browsing garage sales or flea markets.
• Visual Growth Diary (GrowthLogView): Track height (in/cm) and weight (lb/kg) on an interactive vector chart displaying the official WHO reference curves (3rd, 50th, and 97th percentiles).
