Hi S.!
I saw this note pop up the other day and didn't have time to respond. Just wanted to let you know that your grandson is at that typical, prime-time age for seperation anxiety. Lack of consistency in his daily routine (custody not being worked out yet) are probably intensifying it. Also remember that babies, kids are more sensitive than we often realize to how their caregivers are feeling. Stress, sadness, anger are all things this little one will notice.
Best thing you can do is be as consistent as you can be with routine, expectations, etc. while your grandchild is in your home. He will learn what to expect when he is there, and that will help him feel safe - the most important element in the development of a happy child. It sounds as though he is already SO loved. Yeah for you for supporting your son. He is still so young.
Six choices for food is overwhelming. Two or three is perfect. Also, my children are often not as hungry in the evening. Not to worry. Worry about a child's eating habits is far more damaging than the habits themselves. Eating and pooping/peeing are the two things a caregiver cannot control - and an area where a child will prove this to you if he feels out of control! I believe a child knows his own needs as far as when he needs to eat, etc. and even though we may have good intentions, we mess it up sometimes. {Prior to becoming a teacher, I worked in early childhood (with infants and toddlers) for over 10 years.} I saw many potty training issues and eating disorders caused by parents who thought they were going to just make the child do what they thought they should do! A caregiver can and should, however, set certain limits, expectations (lovingly and patiently) and BE CONSISTENT, BE CONSISTENT, BE CONSISTENT!
Absolutely foolish to give the baby juice before dinner. Have water available to the child througout the day, and I cut all snacks/drinks off an hour before meal time. Milk is offered after they eat dinner. If the child drinks throughout the day, this will not be a problem. I give diluted juice following breakfast time and that's it.
I'm sure that as things settle, you will find what works for your family. I wish you all the best!
