Hello first time mum, don't worry u r not alone. Almost all mothers experience this however it is good to munch on something healthy although there will be few cheat days. It is better to avoid the ones with preservatives or highly processed food till delivery. I used to toast a bread and eat with peanut butter. Sometimes I will eat nuts and dry fruits. I also used to keep digestive biscuits which are rich in fibre and filling too. Keep cut veggies in fridge ready, if you really feel hungry you can add cheese, olive oil, tomato sauce or any salad sauce of your choice and eat it raw or can stuff in bread/wrap and eat.
