Hey hun,
Just keep persevering, BF for me has only just started to get easier in the past cpl days & Sienna is 3 weeks. I had these probs around 1 week too when my milk supply was coming in & my boobs were really full, they felt really hard, she couldn't attach properly. Massaging the areola and expressing a little before a feed helps and also heat packs on the breasts before a feed helped too.
Also Sienna still pulls off alot, I think my letdown is quite full on and she can't keep up so could it be this?
Can you call the ABA or a lactation consultant?
