I bet you are pretty familiar with relative space after that kid of yours. How can you put so little in and get so much out, right? You should probably get the 100% cotton Doctor Who Tardis Infant Snapsuit just to drive the point home. Okay so diaper jokes thrown to the side, the Doctor Who Tardis Infant Snapsuit has both a front and back print emulating the famous police call-box/ time vessel of the super groovy Time-Lord, the Doctor! Unfortunately, the Doctor Who Tardis Infant Snapsuit does not make the TARDIS sound effect but it is perfectly acceptable if it is your child's first 'word'. Whatever works, right?
