Thanks for paying it forward nluno
Great advice there
It does look like cutting straight to one nap now is the way to go. Not sure what time you put her down for nap today as we are in different time zones, your post looks like 9.04am to me but I know it wasn't at 9am as you gave her lunch at 11.30 and then nap
PP suggested 12.30 for nap and this can work out really well, if she struggles to get there then I'd say 12 for now and watch out for when she needs it moved a bit later. With a 12 (or slightly later) nap her WU time in the morning should hopefully return to 7am, her usual time.
I also agree with pp about BT - set nap and BT works much better for LOs this age and on 1 nap but try to fix the "set" time to what works well for LO. if she has always done a 12 hr night then you can likely still look at 7 - 7 but she might need a longer night (6.30 - 7) on only one nap or shorter (7.30/8 - 7am).
Honestly the second year was the worst for me with the constant teething. I remember it well. Medicating before nap and night sleep might help, I used to save a dose for giving at night too during the worst times.
I had a little foot stool in my DS's room by the cot which was nice and low to get me the right height without bending, and shoved my arm through the bars to keep a hand on him...I think my head was likely resting on the bars at 3am too wanting to sleep! Perhaps you have a small step stool or similar you could try out? TBH although we all want to avoid bad habits if you know she's struggling and needs a hand I'd just do it, I found with mine that as soon as he could return to independent sleep he did, he didn't want me in the room any longer than he actually needed me. I think with a LO who is used to sleeping independently they do generally go back to self settling just as soon as they can. If you keep in mind your goal, to support and reduce, then you will be fine - reducing the weight of your hand when you can, leaving it there only the amount needed to sooth and not more etc. I'm sure you know the drill.
Like I say that second year was hard for me - sore back, loss of sleep etc. I clearly remember when his canines stopped hurting and we had a clear three days and nights of independent sleep no problems, bliss!! And then the second year molars started and I just could not believe it!
Many hugs from me. Keep telling yourself you will get through this, it is not for ever, even if it starts to feel like it - but do sort out a better position for your poor back!
