My 3month old DD has started making this straining noise, like she's constipated. She strains and straings, and often curls up (as if she has a stomach ache). She is exclusively breastfed, so I don't think she's constipated. Some of the time she eventually farts, or I burp her, and she stops, but a lot of the time, I can't figure it out. She rarely poos after, and if I pick her up, she just stops and is all happy. Even if I don't pick her up, and just distract her with a toy, she's all smiles again.
She does it all through the night too. She's normally a great night sleeper, just wakes up twice for a feed and goes straight back to sleep, now I constantly hear her straining. I tolerate it for a few mins, but after maybe 5 mins, I just get worried that it means something, and end up feeding her or changing her. It's getting really frustrating now, coz it's been happening for about 7 days now. Anyone got any ideas?
