My twins are 3 next month and have to say have had a very peacful and quiet 3 years as far as bedtime is concerned, am moving them into beds in 2 weeks.
And i feel all hell will break lose when they realise they can escape at bedtime, they will be sharing a room, and am dreading it, am sure all you multiple mums out there must have a few tricks up your sleeve, so that bedtime is still peaceful and destressful, love it at 6.30 when i have a couple of hours to recouperate, feel this may be now a thing of the past.
