LO 13w old, been sleeping through, now waking at 4-5am for feed

[cgmom]

Hi there, I would just like to get your thoughts on this:

My LO had been waking up for her "night feed" as late as 6.30 or even 7.30 am, but since last week she's started waking up at 4.30, then 4, last few days at 5.00. It is very unlike her, because she had been pushing her night feeds later and later since the beginning, and had been doing 6am or later since she was 9w old.

I wonder if you have any ideas what might be causing this? She gets a df Aron 10.30pm, has always taken only about 1.5-2oz at that time.  She was first bf, then around 10w starting refusing boob and slowly phased out bfing, and is now bottle-fed. That didn't change around the time the wakings started, so am guessing not related.

She was also struggling with 30 min naps, which we're working on, but which meant that she would sometimes need to be fed more often than the 3hrs, to accommodate for her nap times. Again, the improved naps only started a few days after the 4am day.

Any ideas would be greatly appreciated. 5am is not bad I guess, but it just confuses me as she'd been so consistent with waking up later and later.

Thanks!

What is your routine like?

At this age, my LO started waking earlier.  We had a lot of issues going on.  His routine was a mess and he was in the middle of a growth spurt.  Anytime my Lo went through a growth spurt, he woke earlier to eat.

Was wondering about a growth spurt, but she doesn't seem more hungry than usual during the day.

OUr routine is roughly a 3hr EASY, with some EASAS cycles in there due to short naps.
Here is an example, of course some days are more of a mess than others.
A 8.00 awake
E 8.15 generally not v interested in eating at this point, small bottle with lots of interuptions (nappy, etc)
A 9.00
S 9.15/9.20

E 10.15 (if short nap, I offer the rest of the 8am feed, as she seldom finishes it)
A 10.30
S 11.00 (shorter A time due to short nap)
(here she sometimes manages a 2 hr nap)
E 13.00
A 13.30
S 14.15 / 14.20

A awake again around 15.00 -15.15
S 15.45 short nap

E 16.30
A 17.00

E 18.00
S 18.15
bath 18.45
E19.15 before bed
19.30 bed

Been thinking about it and here's some more details on how she started waking up and what I did:

Night 0
Bed 7.30 pm
Awake 6.45 am - bf for 45 min (was still trying to keep the one bf session as this seemed to be the only one she wasn't objecting to)
7.30 - tried to put her back to bed, she sometimes goes back for another 1-2 hrs. Didn't settle, took her out.
7.45 bottle - approx 2 oz


Night 1
Bed 7.30pm
Awake 4.30am - bf without interest for 30 min. Unsure of supply , went to get bottle but she was asleep by the time i got back, so I let her sleep.
Awake 6.30am - offered bottle, had 2oz. then back to bed.
Awake 8.00am


Night 2
Bed 7.30pm
Awake 4.00am - bf for 30 min, then offered bottle, had 1oz
Awake at 8.00am

Night 3
Bed 7.30pm
Awake 4.45am - bottle, had 1-2oz, then fell asleeep. I didn't try wake her up, thinking that way she would continue to get her calories during the day instead of night.

Night 4
bed 7.30pm
Awake 5am - bottle 2oz
awake 7.30

etc

Last night was first time she had 4oz, which is the size of an average daytime bottle for her.
I'm thinking this is going backwards, if she starts eating more at 5am. However I've been trying to get more in during the days, without much success. Some days she's really not interested in eating in the morning, some other days she's starving, but then it evens out during the rest of the day.

Is it allright to try offer less during that night feed? How can I get more in during the day? I regularly burp her and take short breaks, after which she's interested again, but really can't seem to get her to take more than approx 4oz/125 ml at a time. We still cluster a lot in the evening between 6 and 7.30pm.

Sorry for the lengthy post, but I'm hoping someone will have some suggestions I can try out.

Thanks!

..and another question re:the df - she only takes about 1-1.5oz (very rarely 2oz) at 10.30pm. Do you think its worth continuing or should we just give this up? Its been going well, in the sense that it doesn't seem to disrupt her sleep, but do you think its helping her sleep longer?
