I swear someone swapped him on Thursday night for a grumpy baby who looks like him!
DS will be 4 months old tomorrow.
He has been having green poo nappies since Friday, although we have had a couple of yellow ones today, doesn't seem ill in himself but just very windy/colicky. He isn't happy latching on unless he is nearly asleep (except bedtime feed this evening, he latched on fine), just screams, cries, thrashes about and then will either burp, trump or poo and then will latch with some encouragement. This is the child who would never say no to a bit of boob :o
Just seems generally grumpy, is dribbling like mad, has gone from sleeping 8pm til at least 4am to waking at 2am, 4am and 5.30am the last few nights.
He did roll over for the first time today (typically he waited til I was out of the room lol) which would maybe explain some of the changes in his behaviour but I don't understand where all the tummy gripes seems to have come from - he has never been a particularly windy baby, he is ebf and nothing in my diet has changed.
I have literally spent all day walking around with him on my shoulder, except for a trip to supermarket where he was perfectly happy. I have 3 other DCs and I'm shattered, I'm sure it's only a phase but I want my happy baby back :( Not helped when I was having a moan to my best friend about it all and her response was 'well, that's what you get for breastfeeding him' and 'he's attention seeking because he's constantly attached to you' 
Sorry for the rant, just needed to get it off my chest I think!
