Bought this for DS (now 10 mths) a few months ago.
When he has a winter coat on, the straps are pretty snug and hard to do up, despite being at maximum extension.
Mamas and Papas did send me new straps, but they were virtually the same size so it did not help! I emailed back to inform them and they have washed their hands of it, albeit politely! I have said that next year, the straps will be too tight, which means I won't be able to use it and so would not be getting my moneys worth....waiting to hear what they say but meanwhile, thought I would see if others have this issue? DS is average height and weight btw so not like I have giant baby straining at the straps!
