My baby is 6 weeks and spends a lot of time making noises that sound like grunting and straining. He's been doing it since 4.30 this morning, without really waking up. He's also difficult to settle and almost impossible to burp, even if I sit for 20 minutes rubbing, circling him, putting him across my knees. If he doesn't burp he sicks a bit when I put him down. He's pooing once or twice a day, leading up to it with loads of farts and a red face. My HV says bf babies can't get constipated but he's clearly in some discomfort and it's affecting his sleep and ours. How can I get the wind up?? I'm using infacol to no real effect. My first DS was (is still) a prolific pooer and burper so I'm at a loss. Any failsafe tips??
