Nothing causes parental guilt to kick in faster than a little one pleading to stay home with you. Indeed, it's not unusual for 2-year-olds to protest going to daycare. They may resist getting dressed in the morning, say they don't want to go, cry in the car all the way there, hang onto your leg for dear life when you're ready to leave, and perhaps even play the "sick" card — particulary if they've heard this ploy from an older sibling.
Your child craves your attention, and separations can be hard for him. Instead of trying to avoid daycare, he probably just wants to spend the day with you. Keeping him home isn't always feasible, of course, and you don't want your child to believe that he can get out of daycare whenever he wants. If you're sure that your child isn't ill, continue with his normal morning routine. Still, think about whether the two of you are spending enough time together. Would getting up a little earlier so you have time to snuggle together, read a book, or play a game help him feel better?
Consider, too, that your child may be anxious about all the new faces and rules at daycare, and think about whether the setting might be too large or impersonal for him. If you're generally happy with the quality of his care, ask his caregiver if you can bring him in a few minutes before the other kids arrive. This will make daycare seem less overwhelming and give him a chance to ease in without other kids vying for his caregiver's attention.
His daycare provider can also try to pair up your child with a new friend by making them partners during activities and seating them together during snack or circle time. With an ally, your child should feel more comfortable away from home and is less likely to say he's sick when he's not.
