If possible, perhaps a quiet room however in reality this may be hard. In the past have found breastfeeding necklaces useful – they are designed to help bubs interested for longer

Nursing in a quiet, darkened, boring room often helps. Talk in quiet, soothing tones (if you talk at all). Nurse while lying down; nap nurse. Cover baby with a shawl or put him in a sling to nurse. Nursing while in motion (walking, rocking) can also help baby to focus better on nursing. Try to catch your baby when he’s more willing, such as when he’s just waking up, already a little sleepy, or actually asleep. Baby’s initial pulling off is probably not an indication that he is finished – just an indication that he saw/heard something interesting across the room. When he pulls off, try to coax him back to the breast a few more times before giving up.
If baby pulls away without letting go, keep a finger ready to break the suction as soon as he starts to pull away. You can also nurse baby in the football (clutch) hold so you have better control of his head, or nurse him in the cradle hold in a sling.
If baby is not nursing as much because of distractibility, offer the breast often (even when he doesn’t “ask” to nurse). Make up for lost time by nursing more often during the night. Older babies may nurse better if you try different and novel nursing positions in which they have more control – baby standing up, sitting on your lap facing you, etc.

Haha its a tricky one! If possible a quiet room. If not perhaps a small toy they can hold/fiddle with while feeding? Goodluck, it’s not easy

You can by these little clips to attach to your top which has like coloured beads on it which encourages the Bub to focus on that while feeding, not sure what they are called but I’m sure you can google it

Pick a comfortable, secluded spot in the house, preferably where you son close the door. May not be an option with another child, but you didn’t specify age, so it might be an option

yeah have to get him somewhere quiet or see if he is just happy to sit there and watch all the commotion of the household.

Try and have a lie down on your bed and take him with you and feed him there, you never know he might even fall asleep as well while feeding
