My son is 27 months old and our pediatrician recommended we seek early intervention at his 2 year well check. He was not speaking very much at all so we agreed and he stared seeing two therapists. His speech therapist is great and a breast feeding advocate and said she saw no reason to wean him even though I am 6 months pregnant. He only nurses before nap time and bed, and throughout the night if he wakes (we co-sleep). His occupational therapist made a visit yesterday and said his speech delay was most likely caused by the fact that he still nurses. I find this highly unlikely and can't find any evidence to support this. He always refused a pacifier and stopped drinking from a bottle by age 1... He does still use a sippy that isn't ideal since its not a straw or tilt cup and requires him to suck. I know the sucking mechanism for using a bottle or pacifier or even his current sippy can delay or affect speech, but I cannot find any evidence that supports breast feeding is the same. If anything I'm seeing quite the opposite since a different sucking mechanism is used when nursing. She told me to wean my son as soon as possible. I'm quite shocked and confused. Is this really truth, can breast feeding cause a speech delay? I have a hard time believing her or taking her advice because she also initially diagnosed my son with a sensory delay, which after a few weeks she told me he didn't have any signs of at all. She also made comments like "you don't want to have to be nursing both children" and "if you don't wean him now, he will be jealous when you nurse your new baby". Wouldn't the last statement be the opposite? I'm 3 months away from delivery and if I wean my son now, when he sees me nurse the new baby I would think he would feel jealousy and mild abandonment, especially since he can't communicate well enough to understand the concept. I really don't want to stop because it's the only comfort my son has and we have tried to put him to bed without nursing and it's nearly impossible. Granted it's become frustrating since his latch is no longer strong and he will commonly gnaw on me with his teeth, but my discomfort is the least of my worries. We are thinking of transitioning him to a toddler bed soon and I think that plus weaning AND a new baby would surely traumatize my son. Should I take this woman's advice, or politely tell her I've done research and don't feel comfortable weaning at this moment. Ultimately I want to do whatever is best for my son.
