34+4 baby girl already playing with her dad

So I wake up my fiancé at 4 in the mornings 3 days a week. Our baby girl has gotten used to this schedule because she’ll wake up with me, he decided to lay in bed a little longer and put his hand on my belly and she kicks him he then gives my belly a very light shake(like trying to wake someone but not startle them at the same time) and when he does this she’ll kick him in response well he ended up falling back to sleep and when she realized the shake was missing she kicked harder he didn’t budge lol. She kept doing it for a good 2 mins before she realized the shake wasn’t going to come.I think it was the sweetest thing that they were bonding this way. It brought a smile to my face.
