Congratulations on your pregnancy! There are so many documented advantages to breastfeeding your child (for both mom and baby) that I always suggest women try it.
Most women with implants are able to breastfeed because the implants cause very minimal disruption of the breast gland itself. Even if the implants are sitting submammary, the dissection usually doesn't disconnect the gland from the nipple.
You can expect the usual amount of breast expansion/engorgement with breastfeeding and the usual amount of breast deflation and droop that most women experience after finishing breastfeeding. This means you may need a revision surgery in the future in the same way that many women request augmentation or mastopexy after pregnancy.
There are no documented risks to babies - a study was even completed on women with silicone implants and there was no evidence of increased silicone in the breast milk.
Breastfeeding is difficult for many women - even those who have never had surgery on their breasts. Stick with it and get some support - try contacting your local La Leche League or attending breastfeeding classes or support groups. Breastfeeding is well worth it.
