I never really liked the concept on the P&T (particularly once the youngest goes into the lower seat) but it seemed like the best option for two under two so I went for it anyway.
DS is 3 months and DD is 21 months, I've been using the P&T since DS was born but even though he's not particularly big the lay flat bit is getting too short. I need to take a potty for DD with me when we go out and there is no hope of keeping it in the shopping basket without disturbing DS twice every time she needs a wee. I put it under the top seat and DS kicks against it, which can't be nice for him! I had to stop using the cocoon a few weeks ago, that was a right royal waste of money.... The brake is a total PITA too. Grr.
I've got a bugaboo as well as a maclaren triumph and both are fab in their own ways. If DP and I go out together with the DC we can use those two. I'd like to use the bugaboo with a buggy board later but I think that might be hard going for DD on longer journeys. TBH it's also handy to have her strapped in when I'm on my own with them both. 'tis probably an option from next spring though.
So, are double maclarens any good? I've never seen one in RL, are they very wide/cumbersome?
Oh, and from what age doesn't DS need to lay flat?
