Well, the answer to your question is whether or not you are comfortable with it. If you want to EBF until he's 6m old that is your choice.
If you're asking an opinion health-wise if it's ok. I think it's totally ok. My dd was EBF until she was 4m old. We started her on veggies but she hated it so she got cereal at about 4m old. I never gave it to her in a bottle because it's not recommended out of a bottle. HOWEVER, I know a ton of mom's that do and as long as it's incredibly thin I think it would be fine.
It's a delicate situation because, though I do believe that babies will eat when they are hungry, EBF babies really prefer the breast.
My dd would go all day w/o eating because she wanted the breast. It's very common. So, just weigh if it's someething you want to do or not, if you think it's in his best interest or not.
But if you do, he'll be fine.

rshovan said it well. It is fine for him to have rice cereal but its really up to you. I personally waited until my girls were 6mo. Is there a reason she gives it to him in a bottle? Can she just give it to him with a spoon? My girls still wait until I get home to BF. I guess it just tastes better from the tap ;).

Well I am still really new at this mom stuff and when my dr said incorperate cereal into his diet both my mom and my MIL always thinned it out in a bottle? I have just been turning to them for advice and didn't even realize it should be spoon fed. That is just the way I grew up and then when my MIL did it to i figured it was the right way. They both raised 4 kids each. I think I will try it by spoon since he really does hate the bottle but I do think I might wait till 6 months.Thanks ladies.

I'm not against rice cereal...BUT in the bottle Ive heard they can choke and ingest into the lungs..so if the baby is having it should be spoon fed. I gave my daughter cereal in the evenings...trying to fill her belly.

Way way way back in the day they added cereal to bottles and fed babies..even sold special bottles for it but times have changed.

It's ok to do whatever U feel is right..Ur baby Ur choice:) Good Luck

I know a three time mom that EBF her three until they were one. YES ONE!!! Her babies are BIG. They are even a little chunky. I would say that you go with what feels right. If you feel like EBF is the best thing for your family then that is what you should do.

Thanks for this post. we just had DS's 4month checkup and the doctor said that he is 'ready' for cereal/veggies whenever I am. I love that he is EBF and I'm hesitant to start on anything - I just give him tastes for now and I will probably start on cereal before 5 months because he gets so jealous when we eat.
