We've been having problems finding a onsie that can fit a special needs older child. The largest toddler ones were too small and adult bodysuits were too big or had no snaps. This fits great, is cool enough to go under a shirt in the summer and provides easy access to diapers and gtubes. The neckline is also low enough to not interfere with a tracheostomy tube and it protects the gtube from being being snagged during physical activity.
