Despite dd having sucking power that could have unblocked drains, I found it really hard. Nothing like it said in the stupid Emma's diary, I think it was, that was dished out 14-15 years ago.
I got really uptight about it, and was desperate to continue. Eventually, after a bout of mastitis, I slipped in the odd formula feed. I was told to decide how many bottles a day to give - which seemed rather odd at the time, but later made sense. In the end, after about 12 weeks, it got really easy, and I was so glad that I'd persevered. After she started solids at 16 weeks, the norm at the time, it seemed such a shame to stop, and so I carried on until I went back to work when she was 6 months old.
In the end, she stopped when she was 20 months old, after a horrid cold at a new nursery, when she was so bunged up she couldn't suck and swallow.
A La Leche League counsellor really helped, but the thing that was most helpful was relaxing about it, and dropping infacol, which I found useless, for gripe water after 4 weeks as dd cried all evening, every evening.
The other thing I found helpful was to have a sleep, if possible, in the afternoon which helps increase the hormones that help with milk production.
The really lovely thing was that when dd started talking, she could remember being breast-fed, so I was glad I'd carried on.
