Onesies with mittens?

Ne

I live in Canada and the temperature has just started to drop so I'm worried my son (11 weeks) will be too cold - especially in his hands.

He's currently sleeping in long-sleeve, feet-covering onesies, but they don't cover his hands. I tried regular mittens and even long socks but he's been able to take them off since he was 2 weeks old...and his fingers are usually cold to the touch. 😬

I'm headed to Pennsylvania in a couple weeks and figured I would try finding something with attached mittens, but have no idea which stores would definitely carry them (I hate shopping so would like to avoid entering multiple stores). πŸ™ƒ

Any ideas? Please and thank you! 😘
