Nursing Negligence

I am currently in a custody/visitation dispute. We have temporary orders for visitation and joint legal custody. I have sole physical. We had 3 joint visitations to re-acclimate my son with his father (who disappeared for 4 months after filing suit). My child is still nursing every 2 hours, and it occasionally coincides with visitation as he is not on a strict schedule. His father gets really annoyed when I have to nurse our child during visitation and pretty much keeps telling me I have to figure out a way to get him to eat just before visitation or else he won’t eat. He as much as told me he’d keep the 2 hour long visitation and would not bring our son back to eat unless I agreed to give him extra time with him (90 mins travel time for round trip plus 30 minutes feeding time). I feel this amount of time is unreasonable, as his total visitation is supposed to be 4 hours, and i don’t feel that travel should be “free time”.

If he were to not bring him back when he knew he needed to
eat, could/would that be considered negligence?
um, why don’t you lactate and try feeding a baby every 2 hours and then try to also get supplemental meals from your breasts? i HAVE a breast pump and i HAVE tried pumping, so much so i gave myself clogged milk ducts and i still only got a total of 1.5 ounces from pumping for 2 1/2 weeks.
