mcm, you can call any of the bf telephone helplines, who I think will reassure you. If your little boy sleeps well at night, then he more or less has to feed often in the day simply to get his calories in!!
It is normal for babies to want cuddles and comfort between feeds, and to want to communicate with you and with others. That's how they learn, and responding to this is not to spoil them in any way at all. You might expect this need to be even greater in a baby who has been poorly, and who has had surgery.
In time, he will take pleasure from a wider range of things and people, and be able to be entertained, and entertain, in a growing number of things.
But it is normal for human beings to prefer social and loving contact to being on their own. A young baby is not that good at entertaining himself, anyway. All this is also affected by personality, and it is good to be sociable and chatty in this life! Why do we think it a nuisance or a sign of bad behaviour in a baby???!!
Your baby is lucky to have a mum who is able to respond to him and understand his need for contact.
It'll help you to meet other mothers and fathers, so you can have some adult company at the same time as caring for your baby. He'll probably enjoy it too.
