We visited the pediatrician, and my baby weighs 7900g and is 70cm tall. The appointment was mostly silent: the doctor reviewed a lot of papers (ultrasounds, tests, reports), and the young pediatrician recommended further examinations before coming back when we have more information. We have a medical exemption from vaccinations until the examinations are complete. What's the issue? I've written before about our problems – my baby is 8 months old but doesn't crawl or sit up. A month ago, he still wasn't rolling over, and I was going crazy with panic, crying and running to doctors. You make a doctor's appointment, and time drags on impossibly, waiting to find out what's wrong with your baby. But it's all in vain! In a month, no one has figured out what's wrong with him or why this little one isn't exploring the world like other babies. He just lies there, and that's okay for him. He babbles, smiles, laughs, but by 7 months, he wasn't even rolling over. Now he's 8 months old. We've been going for physical therapy and massage 3 times a week all month, and we'll continue, because, thank goodness, he's started rolling over actively (onto his tummy and from his back) and spins around on his tummy, and he's moving his arms forward. This means his support is good; he started rocking on his hands a couple of days ago. Subtly, he can move backward – he pushes off with his hands and moves backward instead of forward. Now, the physical therapist and I are trying to teach him to squat, but so far, without success. Lifting his bottom and bending his knees is an immense, difficult task for him, and he starts crying and protesting. He stubbornly refuses to stand up and crawl. He cries almost constantly during physical therapy, but as soon as the session ends, he's a happy, smiling baby again! He also often doesn't want to roll over "on command" for a toy. But if you don't focus attention on it, or even leave the room and leave him on the mat, he'll roll over, spin around, and crawl away backward off the rug. We're being examined at the regional diagnostic center. Based on the tests, they haven't fully determined what's wrong with us. They've scheduled needle electromyography for November 9th. Oh God, I read about what that is, and I felt sick. I want to cry thinking about having to put my little son through it 😭 I sit here wondering if we need to do this and why. If these are developmental peculiarities, then perhaps physical therapy will help if we continue. Especially since, in addition to sessions with the specialist, I also work with him at home on days we don't see the specialist, and we do some exercises throughout the day if my baby is in the mood. Who has had this procedure prescribed for them? How did your child react? Did it help understand what's wrong with his muscles, and will it help find the cause of the delayed psychomotor development? His skills include: he's learned to wave "bye-bye" a little (intermittently, depending on his mood), points to mommy's nose, also depending on his mood. He pokes at things with his fingers and grasps them. He babbles various syllables, sings his own little songs with drool and bubbles, and sometimes imitates the cat's meows. He loves "pat-a-cake," but he doesn't clap on his own yet; he only claps my palm if I put it out and say "clap-clap." He eats meat with vegetables from jars, Tёма classic cottage cheese, and various instant porridges. Today, I gave him a dairy-based one for the first time, and we're monitoring his reaction. Before that, I gave him dairy-free ones made with breast milk. Two bottom teeth are growing, and two top ones are about to break through any day now. The teeth aren't bothering us much; I don't apply anything or give pain relief. Maybe he sleeps a little more restlessly at night than usual, but given everything else, it doesn't worry me at all. I'm tired of worrying and not understanding what's wrong with my child. Why is he developing so slowly and missing all the milestones. Sometimes I'm very scared, then it passes, then I get scared again, and I fall into despair. I don't feel any joy when another date arrives and my baby gets a month older. I wish I could stop time and give my child a head start. But unfortunately, time flies, and my son isn't in a hurry at all, and I'm scared for him. By the way, we've also been scheduled to see a geneticist on December 10th 🤦️, why so late? This is Krasnodar... but I don't really know how they can help here. Who has dealt with this? What do these doctors do, how do they treat, and how do they examine patients? So, that's how things are with us at 8 months old. Instead of the joy of motherhood, panic and despair often overwhelm me. Please share your comments about geneticists and electromyography; I'd like to learn more about it.
