Sorry just seen this as was out yesterday - tbh op if not even pregnant yet then don't worry about what help you may or not need till you are preg - may take you ages to conceive so ages may be totally different hence so will you needs - both may be at school for example
Soothe pat is a bit like The baby whisperer method - tho think all
Books have some methods to a certain degree
shh pat is roughly swaddle, sit, and shh pat rather then letting them cry so that babies don't get very distressed
When dc shows sleep signs or it is nearing their sleep time if in a rough routine (hopefully) dim the lights, etc to set stage, swaddle, the sit with dc w/out moving or noise for at least 5 min until totally relaxed. Then put down. If dc fusses then either rub/pat tummy and say shush shush
Or to pat their back (obv as baby will sleeping on back) so need to tilt on their side so can pat their back and as above - pat and shush
some books advise to pick up over shoulder and say shh while patting the upper middle back but i prefer not to pick up unless have to as can get into habits of keep picking up at every noise and baby then expects cuddles etc
This method does work - better on under 6mths and personally i think better on under 3mths - I usually start mn position when baby is 3 weeks or so - no point any earlier so the shush pat works well with this age
Why does baby wake? Hungry? Habit? Make sure has enough milk during the day. Give a dream feed at say 10/11 and try the pat shush method
Hope this helps :)
