Quick Answer:
Set up a short, consistent goodbye routine; give your child something small to hold onto that reminds them of you; talk to the teacher if it lasts more than a month; and leave without looking back after saying goodbye.
You arrive at the preschool gate. Suddenly your child grabs your leg, buries their face in your pants, and won’t look up. They’re crying “Mommy, don’t go!” and “I want to go home!” The teacher comes over to help, but they hold on even tighter. You’ve been trying to soothe them for five minutes, and it’s not working. Other parents are waiting behind you. You start to wonder: is something wrong? Does everyone else’s child go in easily except mine?
Create a fixed, short, predictable goodbye ritual
Many children find it hard to separate simply because they don’t know what will happen after you leave. You might try repeating the same short goodbye sequence every day: squat down for a hug, a kiss on the forehead, one short sentence like “I’ll be back to pick you up at 5 o’clock,” then hand them directly to the teacher and walk away. A predictable routine can help many children feel more secure because they know what to expect next.

Give your child something small to hold onto during the day
Some parents put a small photo of themselves in their child’s backpack, or draw a little heart on the corner of their blanket, saying: “If you miss me during the day, you can touch this little heart — I’m thinking of you too.” Some preschools allow a small comfort object (like a soft toy or a little blanket) to be brought along, which can help bridge the feeling of safety from home to the classroom.
If crying lasts more than a month, talk to the teacher
Many children begin to adjust to preschool within the first couple of weeks, though some may take longer. If your child is still crying nonstop every morning after a month, the teacher may have helpful observations. Some schools allow parents to sit outside the classroom window for the first few days, or to start with halfdays before moving to full days. Working together with the teacher often helps more than trying to handle it alone. Also, check in with yourself: could something be making your child uneasy at school — like a stricter teacher, or conflict with another child?
One final thought: try to avoid going back to check or watching through windows after saying goodbye.
Some parents, feeling guilty, stay outside and watch through the window after dropping off. Many teachers have noticed that if a child catches a glimpse of a parent outside, even after they’ve begun to settle, their emotions can spike again — and dropoffs may become harder the next day. Saying goodbye and walking away may sound tough, but many parents find it helps their child get used to the routine more quickly.
