This video shows a one month old baby, getting impatient and grizzling at the breast while he waits for milk let down.
It is quite common for baby’s to grump like this, and it can be stressful for mum while she gets everything sorted.
You can see in this video, the baby doesn’t initially have a full stuck on latch, he is just mouthing the nipple. Then he gets grumpy while waiting for the milk to start flowing.
At the end of the video, you will see that he has a wide latch, his chin is touching mums breast, and he is happily sucking away for his feed.
