Transitioning out of sleep suit

Hey mamas! It’s warming up here in Colorado so we’ve gotta get my daughter out of the magic Merlin sleep suit 😬 She wears it for naps and bed time and she is a great little sleeper... but without it? It’s tough 😣 either way we need to get her out of it... Any suggestions? I’m starting with naps without it but I’m scared messing with her naps will mess with her night and I’m starting a new job so I can’t be up all hours of the night😕 How should I go about this? We have AC but her room is on the top floor and the sun shines in it ALL day so her room sits at about 75-77 degrees, (yes we have blackout thermal curtains and a fan running all day in there) so no sleep suit/ sack is optimal.
