Hi Hon. I'd say it's as simple as he's either hungry or thirsty It's a bit annoying when they change their routine though, isn't it.

They are a lot harder to feed at this age as they're so busy and easily distracted. Try a muslin to cover him or get a breastfeeding shawl. My SIL bought one for me and it's brilliant.

My DD is super busy and I find it difficult to get her to have a decent feed throughout the day but I figure she will settle down and feed properly when she's hungry/thirsty so I don't worry about it. I can't force her to drink so there is no point worrying about it.

I offer DD a feed anywhere from 2-4 hourly throughout the day. My goal is to give her 5 feeds a day and as she sleeps for 10-11 hours straight overnight, I need to squeeze them in during the day, hence why I offer frequently. If she doesn't want it then I leave it for a while then offer again. I find being flexible like this allows me to get out and about a lot more too.
