For some parents, preschool will be the first time that you have to get out of the house at a certain time. If you've had a nanny at home or if you have stayed home/worked from home with your kiddos, it can be a big transition to then need to be out of the house by a certain time. One of our biggest recommendations (for all ages, but specifically 3/4/5 year olds) is to go out on a date with them.
Take them to their favorite food joint and bring the picture book you made (see previous post). If possible, try to go out with both caregivers and your kiddo so they can know that this is something really important and special. You can bring markers/paper with you on the date and decide what your morning routine will be. Draw out each step (wake up, potty, get dressed, eat breakfast, brush teeth, etc) and have your kiddo draw pictures for each step. You can even ask them what order they would like to do things. Ideally, this will help set them up for success in the mornings because they know what to expect!
As mama/papa, try to think through your new responsibilities too. Consider packing their lunch the night before and setting out their backpack with all of the needed supplies. You can make on-the-go breakfast ideas and let your little one eat on the way. Or you can just have breakfast ready so it is easier to eat at home before you leave. All of these ideas can significantly reduce morning chaos, which we all want!
