I'm a bit confused.... do you mean at the very start of the process I feed her to sleep, and then if she wakes go to the 'plan'? or do you mean feed until relaxed and then put in cot and then go to the 'plan'?
No you don't ever want to feed to sleep (unless it is a night wake up ie at 2am it is ok to feed to sleep) at bedtime it will be a problem if she falls asleep feeding, so at bedtime & nap times ie the start of sleep you want to only feed until relaxed or sligthly sleepy, but awake enough that they would look around in bed, think ok I'm in bed & go to sleep (which probably won't happen if you've always fed to sleep.
To give an analogy if you feel asleep in your bed & woke up somewhere else you go "what on earth is going on here" so with a baby if the last place the remember being is snuggled up to Mummy's warm body having nice milk & then suddenly they are alone in a bed they wake up upset... if they only have "memories" of waking up alone in the cot then they are more likely to get upset when they are put in there as not only does it have unhappy memories, but also it is not predictable... so you need to make sure that they have things that are predictable & also look the same when they semi wake up.
I never really did PD when my children were upset, didn't work for me, so I would stand on one side of the cot & they would cuddle into me (as they stood) but they were in the cot KWIM) & when they got relaxed I'd try lying them down, so kind of an extended PD. So yes you would expect her to cling & want to get out & that would be when you would take lots of deep breaths to relax yourself & calmly say something like "sleep time, lets get relaxed" & rub her back & just show her she is safe & you love her etc & get her to trust that you know what you are doing & it is ok.
I do think it is a bit of try & get her to be relaxed (but not asleep) & then lay her down, but there is always a fine line & I *DO* think with parenting it should never be about "I got that wrong" (cos there is no right or wrong) but to be "ok, I can see that I let her hold on too long & she was asleep in my arms" or maybe I should wait a bit longer if she is going to cry like that when I try to lay her down. it is kind of about finding what works with both of you...The thing is if she does fall asleep cuddling up to you, you have got more than half way there... she is in the cot & she isn't falling asleep feeding, so you could then say ok I'm ready to tackle trying to lie her down earlier & stoke her back while she lies down, & then move to less & less stroking.
I couldn't do cold turkey it wasn't me & so I kind of worked out ways to break down the goal based on where we were & what I could lessen... I mean even last night with my 5yo I ended up stroking his face to get him to relax to go to sleep because I knew he was struggling to relax & the longer it took to get him to sleep the worse his tiredness would be... so you do kind of have to make a judgement call on what your instinct is, if you feel you are helping a bit too much, think what could I do less, could I only pat her back to the count of 5 (when you are doing it to 2) would that work KWIM
A bit random as thinking of things as I go... but another thing is - you CAN NOT make a person sleep, you can help them relax so they are in a position to sleep, so you don't focus on them going to sleep you focus on what is best at keeping yourself relaxed & what can help your child relax.
The reason I suggest at bedtime is normally children are tired & more ready for bed at night & also there is less light & often less noise & if you say throw in a bath etc then there is a more predictable routine & the "predictable" side is an important part.
Finally, she probably will get angry... accept that, you are changing the rules on her & she probably doesn't totally understand, it is good she gets angry, see it as her processing that things are changing, but don't let it do anything but steel your resolve... the 5 stages of grief - 1.Denial – yours - this will sort it self out
2.Anger – Hers - It's not fair!, why us it changing
3.Bargaining – her - the clinging the pleading eyes
4.Depression – both of you, her the sobbing & sniffing & you the "I feel so horrible"
5.Acceptance – Her - I can't fight, I love my Mum & she is here for me.
And yes found the shoes (I think it was my doing) they were 2 shelves up from where the shoes live & I think I probably picked them up from where they weren't meant to be & as I was putting something else in the cupboard on the 2nd shelf, put them there not on the bottom one LOL... shoes have made it there for 2 days since
Oh & if ever you think "Is this the right thing' "or what should I do now" think "am I helping her relax, how can I help her relax" & go down that path... because that is the key to get her relaxed enough to want to sleep (like feeding does)
