The whole idea of Mexican Bolas is lovely. it’s a chiming pendant traditionally worn by pregnant women to bond with their unborn babies. Worn low over theÂ growing bump, the soft tinkling chime of the pendant is said to gently serenade and soothe baby as Mum goes about her daily life. I really like the Liberty print bolas from Blooming Lovely. A great take on a traditional piece of jewellery and, at just Â£18, a great gift for mamas-to-be.
