I just had a thought. maybe you could pick out a 'lovey' for him. Like a soft cute stuffed animal. Cuddle it up to him and put his arms around it, give it to him at bed, etc. My sons had special items like this that they really loved and provided some comfort during the night and things like that. :>)
Sad or pouting? If this is a new behavior---------- he hasn't been breast feeding or trying to use the breast for comfort all this time, I'm not sure why it would start now. You aren't currently breastfeeding a baby right now. When he wants to do it, give him a huge cuddle and then move quickly onto doing something fun with him. Don't dote on it and turn this into a big deal. My kids got sad too when they were told no. But some things are a no. And if he hasn't been breast feeding and he all of a sudden wants to be on your breast, for me that would be a no. he's most likely also not really taking any milk. He's just putting his mouth there and that gets into a grey area of 'not normal' as your post asked if it was or not. good luck
Your only 12 weeks. I'm still not sure what kind of milk you started producing after being done with breastfeeding for over a year. I guess you kept your breast milk going by expressing although I can't imagine why. But that is besides the point. Our breastmilk undergoes changes as a child ages. Newborn milk is very different than our breast milk after feeding a baby for a year. Anyway, Don't feel bad about not giving him a breast. We offer comfort to our children in many ways and better to develop a way of him feeling comforted by you that is more appropriate under the circumstances.
Your baby is long off, I wouldn't make the hugest deal out of it to a toddler. He would have no reason to be jealous at this point. peace
Oh n when I tell him no hr gets sad he won't cry but he puts his head down m gets really hurt so I can't do that to my baby
Well I guess I just feel bad cuz I kow he feels the baby n Its a comforting feeling for him I don't want him to feel like I'm pushing him away for the baby
N plus he's still my baby n well actually I never stopped producing milk from time to time if I squeeze my breast will squirt
Well, I'd say that if you have not breast fed him since he was 9 months old and he is wanting to breast feed, you might just say "this is the baby's food. You had it when you were a baby and now you are a big boy and get to eat yummy big boy food." I would not let him 'try'. that's just me and my opinion. I'd be firm that his time of sucking on mommies breasts is over.
As to pulling on your breast, a simple no usually worked for me. I actually breast fed my second child for a LONG time. he too occasionally wanted to hold my breast for comfort and I'd just take his hand away and hold it, give it a kiss and give him a snuggle rather than let him do it.
Oh, and at your current time in pregnancy and not having breast fed for LONG time, what milk is there?
good luck
