My son is too big for his Doona

I’ll start off by saying I LOVE the Doona. I love it’s design. It’s so sleek and understated yet durable and feels luxurious but not too flashy. However, I’m very sad to say that my son is huge and has already outgrown it at 6 months. He’s 98th percentile (28.5”) for height, 90th (20 lbs 6 oz) for weight. Anyone have any recommendations when it comes to an alternate infant/ toddler stroller/ car seat that has the same look/ feel? I want something nice but I don’t want it to look like I’m trying too hard.

TIA
