We had the opposite problem awhile ago; we had a hot week or so in the city, and hadn't put in the AC yet - the kid kept waking up, and at one point when I went to check on her, I found her having unzipped her pajamas down to her waist and wriggled her arms out of the top part.

Making sure they're well fed is definitely a good idea; my wife was worried that she'd over-associate sleep with eating, and wouldn't sleep without eating first... but I never really saw this as a big problem. She's a baby; let her eat before bed.

But all kids are weird and different - some kids have reflux, and feeding them shortly before going to bed is going to keep them awake. Some get gassy. Some just don't like sleeping with a full stomach. That's probably the worst thing about being a new parent - you can read and listen to all the advice you want, but then you gotta figure out what actually works with yours and what doesn't.
