For all the talk of kink on that page it’s good to remember that a solid 70/80% of the time if I’m with someone I want that to be a gentle nurturing experience - Yes she’s still gonna be infantilised, taped in a nappy with a pacifier in her mouth but it’s less about teasing her / Getting her horny and pent up; and more about softly caring about her, gently holding her in your arms and giving the all the reassuring cuddles she needs. Let her know she’s safe, loved, protected and validated in her perfect little space. Get involved in her playtime however she wants, help her with her colouring and positively encourage her to finish her picture, offer all the love and support a parent would give as you encourage her to be little, lovingly feed her bottles and food, in her high chair, safely tuck her in bed at night after story time, be gentle and understanding with how fragile her regressed safety is and protect her with as many cuddles and as much affection as she needs - her little space is beautiful and encourage it to flourish.
