My 8 week old has gone from being occasionally and predictably fussy to being fussy all the time with a lot of screaming through out the day. He isn't really feeding in the day - And just screams and wriggles when I put him to the breast. He seems to suddenly have very bad gas and for the first time ever has been a little sick when burped. He used to feed fine so I can't understand why this has suddenly all changed at 8 weeks. He is hardly sleeping at all in the day now but thankfully ok at night albeit with a lot of squirming and passing of wind. Have tried gripe water but that seemed to make him worse. He is my third child so am finding it so hard as I can't put him down. The other 2 are basically watching TV non stop as I can't play with them very well with a baby I can't put down. He used to like the bjorn but now hates it and hates his swing and pushchair. It's making me so tired and depressed. Been going on 3 days now - any ideas?!
