Baby congestion relief

My baby has had this since she was 2.5 weeks (although it’s slowly getting better - she’s 7 weeks now). I took her to the gp for it when it was particularly bad and he said it’s normal and “well she doesn’t have it right now so she’s fine”. The HV and the specialist nurse both also said it’s normal and she’ll just grow out of it. Either way, to manage it we used a saline nasal spray and the aspirator just before her bedtime feed every night and then any time it was particularly bad during her night time feeds. Our room was always kept between 50-60 humidity (which is the recommended level for babies so we skipped the humidifier). We also tried a steamy bathroom which did help but again all just temporary relief to manage it. One thing I don’t know if it’s related or if she has just gotten better with age, I started taking an antihistamine for my hayfever just this week after clearing it with the HV and weirdly her congestion has been little to none at all (I’m ebf). I hope this helps!
