Yesterday I gave ds a bottle of ebm for his mid afternoon feed, I've never totally replaced a feed before, just used ebm as a top up. I did a late feed last night, a feed again at 5am and one this morning. All night I've felt very engorged, doesn't help that ds has a bit of a cold so he's not feeding brilliantly, but this morning my left boob feels bruised and there are red marks on it. Is this the start of mastitis? I've expressed after both feeds today as usual but making sure I empty the boob completely but it still feels a bit sore, not agony but definitely tender. I don't have any cracked nipples or any way for an infection to get in. Could it just be a blocked duct and can I just get rid of it with lots of bfing and using a hot water bottle on the affected side? Sorry, loads of questions, just don't want to be in agony over the next couple of days, it's bad enough that my mum has just broken her arm and can't do the lunch tomorrow, I need to be able to do the lunch!!
