Has this doctor lectured you before about something she's not doing yet?
My daughter was born over two months early and my ped has always asked me if she's doing things kids her actual age is doing. But the thing she's always driven into my head is that as long as there are emerging skills (like the pincer grasp for example) then I should try things that are on the timelines but not worry too much about her being "on time". Even at our adjusted age my daughter has shown development for some skills on time and has been WAY late on others. She's 19 months and still isn't walking yet but she will push one of those walker toys like nobody's business. So we are giving her another month before we get concerned about it. Again just an example. Meanwhile, she is talking, knows body parts, uses signs, takes off her clothes and tries to put them on, which are all pretty much on time or early. Every kid is different.
The other question I have is whether this doctor told you to MAKE your daughter self feed or just try it with her? I have misinterpreted things like this with my doctor which is why I ask. When she was TINY, I was sure I had to get her to eat 3 ounces in 15 minutes for a while and then found out that I could just feed her small amounts at more frequent feedings. But I was sure we HAD to eat that much in that amount of time because it's all I heard.
Trust me, she will get it. If she's not ready to do it today, then don't sweat it. She needs her calories more than she needs to learn to self feed as a preemie. Make a game out of it. See if you can get her to feed you a piece of food and then you feed her and then you eat a piece and see if she will eat one. And if nothing happens during that meal, then try again in a few days/weeks. With my daughter I would try things she wasn't ready to do and worry that she was behind. But then I would give up pretty quick and try again in a couple of weeks and she would totally surprise me.
If you are uncomfortable talking to this Dr. openly or dread seeing him, you need to find another one. But if you feel comfortable asking questions and there's a possibility you might have mis-understood when he talked about self feeding, then you might want to just give the office a call and tell him she isn't going along with this self feeding thing and see how big a deal he thinks this is right now. He may tell you to try again later. If he alarms you and tells you that she MUST learn this before the next visit, then I would definitely start hunting for another Dr.
You are doing fine, trust me! Having a preemie trains you from the moment you bring them home to do things to the letter or there will be dire consequences. I think for some kids this may be true but if your daughter is otherwise healthy, just small, then you need to listen to your mom instincts and try to relax a little. I struggle with this every day but I am getting better at it slowly but surely! Good Luck Jennifer!!!
