Okay, so my DD is now 10 weeks old. Since she was about 4 or 5 weeks old she was going a good 5 - 6 hrs during the night, usually her DF was between 10:30 - 11:30pm depending when her last feed was. Last weekend DH and I went away and she was with his parents for the night. Well wouldn't you know she slept from 11pm until 7am! We thought, wow this is great she's now STTN. The next two nights at home with us were great too, 8 hrs one night, 7 hrs the next. Well, then on the 3rd night it all went to hell in a handbasket! She all of a sudden started waking at 3am. She rarely ever woke that early, usually it was 4 or 5am. I just chalked it up to one of those rare nights. Well all of a sudden she's been waking up every 3 hrs during the night. She is also not as interested in taking as much formula during her daytime feeds. She was taking up to 4 oz about every 2.5 or 3 hrs during the day, now she will take maybe 2 oz one feed, maybe a little more other feeds. I am so confused. It's not like I'm not trying to feed her during the day! Could this be a growth spurt? I don't have a set EASY schedule as we are working on some reflux issues and she doesn't wake at the same time every day, her naps tend to be all over the place right now. I've recently switched her formula to a thickened one, but of course the calorie content is the same. She's switched formulas before no problem, it never affected her sleep, so not sure if this is the cause? I will give you a sample day for us, but it varies, and today she was at my parents so I have no idea what her times were:
Eg. Wake at 6am
E - 6am
S - 6:30
E - 9:30
A - 9:45 - 10:45/11am
S - 11am - 12pm
E - 12pm
A - 12:15 - 1:00/1:15
S - 1:15 - 3:15/3:30
E - 3:30
A - 3:45 - 4:45/5pm
S - (this is where it starts to fall apart every night, she's extremely fussy, so doesn't really sleep long if at all)
5 - 5:30
A - 5:30 - 6
E - 6pm
A - usually awake until bathtime which is 7:45pm
E - 8pm (she usually won't want to eat before bathtime)
S - 8:30
DF - 11:30
E - 3am
E - 6am
Like I said, she was going from an approximate 11pm DF until 4 or 5am, now she isn't. I don't know, please help! As I said, this is only one example of many different days. I usually try to go with EASY based on when she wakes. Could be 8:30am one day, and as late as 10am the next. Not sure why her times are different either. Should I wake her at a specific time each day and try to start from there every day thereon? Her naps tend to be all over the place too. The above example is a good day. But lately she doesn't want to sleep longer than the 45 min mark which is very frustrating. I try to help her go back to sleep, but that seems to wake her more, so not sure what to do there either. Thanks in advance for any advice!
