DD 26 months has had 2 late nights in a row now and consequently 2 sleep ins in the morning. She usually wakes around 6:30-7 but last 2 mornings have been 8. During the night last night she woke a few times and then this morning I discovered she had a cold. I put her down for her nap at 1pm but she didn't fall asleep until 3pm. She normally sleeps for 3 hours. If I let her do that she'll wake at 6 and then will have another late night, so I should wake her at 5, right? But since she has a cold should I just leave it? Not sure what to do.
