DS started mostly STTN last week (anywhere from 6.5-9.5 hour stretches) but last night he had 2 wake ups. He had his 4 month shots yesterday and seemed really restless while sleeping (lots of leg kicking, tossing and turning, etc). I'm wondering if it was related to the shots (maybe his legs hurt?) or if the week of good sleep was just a fluke? (He had been only sleeping 3 hour stretches for the month or so prior and we were out of town last week).

How did your LO sleep after shots? Better or worse?
