Oh i wouldn't worry about her going for half a day, she will probably love it!
Jamie goes every morning apart from wednesdays, until 3.30 on tuesdays and until 5 on thursdays (uni day). he really likes it and i need the rest, and my uni time too.
Am thinking of reserving a space for Millie for after xmas, just a morning a week, 9-12. Just to get some actual me time every week, and im not going to feel bad about 3 hours a week
