(4inch monogram on 0-2t, 6 inch on larger sizes)
We use gerber and carter onesies for white, and rabbit skin and gods creation for colored... they run true to size.
Our gods creation brand toddler tees 6m-24m run small so you might want to order a size bigger than you need (or try on in hobby lobby)....
**also carry 3t in white only**
Kids tees true to size: youth xsmall (3-5), youth small (6-8), youth medium (10-12), youth large (14-16)
