I’m ebf my 6 week old, she’s gaining weight and not particularly unsettled. However, from about 2 weeks old her poos have smelt of vinegar but colour and consistency are fine. She sounds unbelievably congested at night and will only take very small feeds before sleeping but then wakes not long after. Can seem pretty uncomfortable on her back for the first 5/10 mins. I sometimes hear swallowing from her when she’s not feeding. She also sneezes and coughs a lot, sometimes has hiccups but not quite every day, quite a lot of spit up but no projectile vomite. I gave her a bottle of formula and 24 hours later she had one up the back loose poo but that could just be coincidence… My first was nothing like this so I don’t know if I’m comparing but just can’t get it out my head it’s something more. Would love to hear any thoughts!
