Thanks for your replies and thoughts girls.

I breast fed DD1 for 5 months but always had a low milk supply no matter what I tried and I did seek help from a lactation consultant. Because of the low milk supply I didn't enjoy breastfeeding at all so I think this is why I want to bottle feed from day one.
This is what happened to me with my girls I only BF DD1 until 4 mths but knew I had no milk at 3 days but I tried to do the " Right " Thing and keep going... It didnt help that she wouldnt take the bottle when I tried to supp feed her... It wasnt until she was 4 mth and basicly straving that she took the bottle ( she had two bottles so she was very hungry )...

With DD2 I knew that I didnt have enough milk from day one so I BF and FF from birth... once again only managed to BB until she was about 3 mths, but as she already had a bottle it wasnt so bad...

As for guilt I felt guilty with DD1 but that was because I could feed DS and couldnt feed DD so felt I was not helping my child grow as she was under weight and wouldnt feed... But with DD2 I knew that as soon as she took the bottle at birth I was helping her get the right amount of food, so have felt no guilt...

I am planing to try to BF again with #4 but wont feel guilty if I cant... You can only do what your body lets you, there is no need to feel guilty about it....
