Can’t contain these thighs

So, I’m having serious issues finding pants and shorts for my baby. I’ve given up on onesies with legs all together. He wears 12 month shirts and onesies, but pants are a real struggle. He’s a generally big baby in all directions, but the place that he’s truly chubby is his thighs. Pants and shorts are just too tight on him. We have a couple pairs of sweats and one pair of baggy shorts that fit him, but that’s it. I’ve tried a couple 18 month pants, and they were really snug too. I know that he’s going to slim down when he gets crawling and walking, but in the meantime, bottoms are such a struggle. He spends most of his time without any bottoms on. I’m seriously considering buying some skirts. At least it’s warming up, so I am not facing this struggle in winter!

Here’s some pics of my cute boy and his chunky thighs.
