Chersam,
Lyn oso can wear those smaller size rompers, but the neckline becomes v big like ur description. So I let her wear bigger sizes too.
totoro,
No leh, actually after term break till now, tmr will be her 1st class. She missed 3 lessons oreadi. =p
Dunno anything abt west side tho.. If really switch, think I will miss teacher peiqin. I like her as I think she is v engaging.
