I need suggestions on getting my husband to be more involved in feeding my kids (with patience). Any ideas on how he can tackle this? My son hates veggies and does not open up to trying out new kinds of food.

You could get your son to help out in making food. The easiest is to get a pizza base and let your son smear tomato or cream sauce on it and choose his own toppings. Try to include more vegetables cut into cute shapes with cookie cutters or dice them really finely. Children will be more open to eating their own creations. You'd be surprised. Another alternative is to get him to choose his own cutlery so your son will be more proactive in feeding himself. As for your husband, if he's very impatient when it comes to feeding your kids, perhaps it's better you take over and he does other chores.
