Hi there
Your DD sounds a delight! Always nice to have a happy baby
Though not when you want them to sleep....
Before you started EASY what was her usual routine? I'm wondering - is the routine you are trying the one which has 2h awake time and 2x2h naps and a catnap? If so, that routine is ok for a 4 month old but needs some adjusting for an older baby to give longer awake times so they are properly tired for sleep - one of the common reasons for standing/laughing when putting to bed is that they are just not tired!
Yes if she sleeps holding your face or hand, that's a prop - even if it's a cute one! In my experience you can 'choose' a lovey for them though
Just pick something you like and keep putting it in her hand at sleep time. You can even hold it in your hand if you use a muslin/blankie and hold her hand through it so she can feel you there but will get used to associating the lovey with safe sleep times. Hopefully that will transition her away from needing your hand. The more 'rip the plaster off' approach though, which in some ways makes more sense if you are using PUPD, is just to stop offering it. Lie her down in the cot and step back so it's not an option for her. You may feel that seems a step too far though in which case a more sensitive/gradual approach is fine.
In terms of night feeds I entirely agree with you
2 night feeds is entirely reasonable at this stage.
Let us know if we can be of more help x
