I feel it takes some forward momentum and consistency to get the daily routine established.Every toddler go through phases of food acceptance ,change likes and dislikes often without rhyme and reason. ..Its perfectly normal. Breakfast has a huge impact on child's metabolism and you can include those foods which gives a kick start energy.You can upgrade the snacks like healthier yogurts which do not have added sweeteners and other ingredients which are not good for the kids health.
