Hi there, sorry to hear you're having a difficult time just after you were all settled into a lovely predictable routine!!
A number of things come to mind:
- illness and recovery can take longer than we expect. Sometimes LOs don't feed so well during illness and whilst they might take on enough to keep themselves hydrated they may need to make up for lost calories by having extra feeds during recovery
- illness and developmental ages often bring on SA which you've already mentioned, you're doing the right thing responding and giving more help when she needs it. SA is just a normal phase we help them through, tiring for us but the more you respond the more her confidence will grow... so keep doing what you are doing
- the cruising is a big step, greater ability to get around can bring on SA, it's a great instinct really and keeps LOs close to their parents rather than cruising off to fall over the edge of a cliff (OK there are no cliffs in your house). she also has a lot of development to process which can have a big impact on sleep.
- teething, sometimes teeth can be on the move even if the gums are not showing signs, teeth move on and off for a long time
- 10 months is a prime time for sleep to go off track, very common, there is a good chance you've hit this stage at the same time as the illness so it's all a bit of a jumble and confusing. 10 months is often the time when LOs need a routine change as they begin the process of dropping a nap. They can retain 2 naps for quite some time yet (ages vary) but some routine tweaking may be needed to get you back onto something settled and predictable
From 2 to 1 nap transition (10-12m and older)Looking at your EAS times, the A looks very short for age. This might be because you have reduced the A due to her illness or because you are worried about OT from lost sleep, or it might be because she was previously doing very well on this time - but now isn't. The freaking out at crib time suggests to me she is UT (under tired) and can look like cot fear or SA when it might be as 'simple' as her trying to tell you she is not ready to sleep yet. A times at 10 months are 3-4 hrs, some get more.
Average A times- BOOKMARK ME! I see in your EAS times you tried for the first nap at something like 2hr 30 but she did not go to sleep until 3hrs. 30 mins of her refusing and you trying to sooth her can feel like a very long time. I know you are cautious to extend A time due to her illness etc, but if you feel she is better now I would go ahead and increase to minimum 3hr A time. If she is used to a long WD for naps then continue as you have previously done but if she is refusing then perhaps take her back out of the room, do another 15 mins A time and try again. Some LO do well on a short WD and can get quite frustrated if taken into the dark room too soon.
Sometimes with these routine changes the NWs and naps only settle once the A time is extended so it can be a tricky patch of being extra tired from NWs but needing a longer A to resolve the day and night sleep. Hope that makes sense.
hope this helps
