It’s a sixth sense, a gut feeling!
If you feel something is not quite right, you are correct. No one knows your baby better then you. No matter if you are a first time mum or a mother of 3. Follow your instincts.
You know how your baby acts and reacts, so if you notice changes in your babies normal ways. Pay attention to the things you notice. Changes in eating, sleeping, activity and their personality. If it’s not their normal then these are changes.
