I finally tried the pacing of the breath with my daughter (although we match our breathing instinctively- we may or may not have co-slept until she was 8) Heh.
But, we did it with more intention with squeezing her hand. At first we giggled, but then we settled in. Afterwards, she calmly said "I really like that".
Very sweet to hear of your time with your daughter - and yes such beauty in the natural sychronization of breath and love that you two share. Glad you experienced also Pacing the Breath together - as it provides another precious and wordless way to connect - at certain social times. Thank your daughter for us and Thank you also. xox ann
