my lo will be 6 months in 2 weeks. Her naps have gotten shorter and shorter. I've been trying to extend her A time,. She just did 2 hr and 10 min and then slept only 1 hr 10 min. She was clearly ready to go to sleep earlier, should I try to push her a little more? Naps this short are really throwing off her day. I'd like her to do about an hour and a half. Any thoughts?
