I'm still waiting to see Twig's play roller coasters, she's been keeping it very quiet considering she only has a month to go! The most I've seen is her jerking up her head when it's booted her in the ribs but I live in hope!
Seriously, usually about with two months to go but each mare is different so keep your eyes peeled!
Twig has held hers up very high, at times you might have thought she was slightly roach backed (but she's not!) and it's only lately that she is dropping her belly; she's made me go greyer than normal, believe me!
