Change in sleeping pattern @ 12 weeks

eltar08 · August 2013

LO is almost 12 weeks and for the last 7 or so after we instituted a bed time routine, she would sleep a 5-7 hr stretch after going down and then 3-4 hrs for the subsequent span(s) - I was very lucky! However, the last 3 days, she has been up every 90 minutes to 3 hours to eat, then passes right back out. She has been eating well both day and night with plenty of wet and dirty dipes. Is there some sort of 12 week wakeful or wonder week? The reason I ask is when she typically has a growth spurt, she is a crazy eater then passes out for a while and I am getting the eating part but not so much the sleep! I am hoping this passes quickly, but was curious if there is anything I can attribute it to.

TIA!
