I didn't even think about lookin at sizes, I just bought! Lol. Elsie's is a bit big but she only wears it when it's covered under tights or sleep suit. Sometimes if she's kicked loads I can find it half down her foot but she'll fill it out soon enough!
Ido believe whole hearted that its made a difference... She's started napping which is something I had been fighting for weeks , and she's so much more contented. She'll lie and play now where as she wanted nursing all the time. And as I said, I've stopped the teething powders and calpol! I'm wondering if they will work if I buy my grandparents one each to help with their problems lol
