Comes to choice. I have BF both my children. One thrived, one did not. My son was a skinny, uncontent baby but I perservied (sp?) til he was 4.5 - 5 months. I then put him on the bottle and he became a happy and contented baby.
My daughter really thrived from BF. She loved it. She was a chubby happy baby from word go. I fed her until 6 months and stopped as she started to bite me and I had to put her into daycare. I found it easier to FF once she was at daycare as expressing and I just never hit it off!
I plan to BF this baby as well but will take it as it goes. If he does not thrive from me I will switch to FF. I should have done it earlier with my first son but thought if I changed that I would be doing the wrong thing by him. I now realise the poor thing was starving all the time! Yet it worked great for my daughter.
As most people have said, take it as it comes. See what works for you and your bub.
