Hi again ...
Was just reading some information that I gathered together from work before I left (from Karitane, Tresillian & Tizzie Hall) - I think that if Summa-lee is only taking 5-10mls before sleep then she isn't really hungry. It would settle her, but isn't out of hunger - possibly she just relies on it to help her settle.
Some info I read that might help:
Babies from 12weeks onwards have waking times of around 1.5-2hrs (incl the feed time) and sleep time 2-2.5hrs.
Karitane suggests a routine of sleep, feed, play. (when 16wks they can have x 2 small playtimes after a sleep, before a feed). They also state that if infants are fed immediately before a sleep, they will associate feeding with sleep time and when they wake out of a light sleep cycle they may wake expecting to be fed - when if they are put to sleep awake, when they wake from a sleep cycle they can self settle.
Sleep cycles for babies are usually 40mins - within this sleep cycle is light & deep sleep, they all wake after a deep sleep - which may be after 20mins - and if all is as they expect it they will go back to a light sleep cycle - if babies can't self-settle they will wake & cry for you to help them re-settle.
Also it states that newborns usually don't 'completely' wake up during a sleep cycle where once 6mths & up they begin to - therefore if not learnt to resettle now it can cause real problems around this age.
*Observe for tired signs
*Ensure bub is comfortable, not hungry, has clean nappy, not too hot/cold.
*Allow a wind down period after playtime, such as a cuddle or quiet time a few minutes before sleeptime.
*Put bub to bed while awake.
*Wrap baby in light cotton or muslin - with hands up near her face so she can self-soothe if needed.
*Follow same settling technique everytime
*If baby is calm then put her on back in cot & leave the room allowing her to go to sleep on her own. She may protest for a few minutes (up to 8mins at 13wks of age) with a cry that has a break in it. This crying is normal for her to wind down ready for sleep (like adults wind down by reading, or watching t.v before bedtime).
*If she needs help to settle (crying for more than 8mins after put down & crying is getting louder & highpitched, walk into her room quietly - don't talk to her or turn the light on - & gently pat her by placing one hand firmly near her arms and pat her gently with the other hand (or rock her cot, stroke her face & head). Turning her on her side & tucking her in firmly often helps and patting her bottom while firmly holding her near her arms/upper body.
*Ssshhhhing her may help as well - if a quiet & consistent tone is used.
*Gradually slow down and reduce the patting as she calms & relaxes (may take 2mins or 30mins).
*Once she is settled, but before she is asleep, leave the room & allow her to go to sleep on her own.
*Some babies enjoy background music played while they sleep - radio station with low volume or relaxing music.
* At 13wks of age you can let her cry (if has pauses in the crying) once you have left the room for 8mins (time it - feels longer than actually is).
*If her cry is continuous & high pitched and you are unable to stop her from crying like this (she doesn't start to calm or cry with a break in between) from patting and lightly 'ssshhing' her, then pick her up in your arms briefly until she is calm, then place her back in the cot awake.
*Continue these techniques for approx. 30mins. If your baby does not settle you may choose to take her for a walk in the pram or carry pouch, give her a massage or a relaxing bath. Then try the techniques again.
*At the next sleep time follow the same routine. Being consistent is what will teach your baby to sleep.
I know this is alot of information ! Hope it is of some help. Am trying all this myself and know how hard it is to really put into practice.
