I only have my one dd since ds doesn’t talk yet but to me it doesn’t seem normal. Dd has always been extremely talkative. If she learned a new word she would use it more but never stop saying other words

Speaking as a mom who was ignored by the pediatricians about the concerns I had about my own daughter.

If you are in the U.S. I would highly recommend that you contact Early Intervention (you can refer yourself) and have them come out and evaluate your child.

At 13 months my daughter stopped making eye contact, didn't point, lost words, and absolutely refused to put weight on her feet and didn't respond to her name. Her pediatrician kept telling me she was fine because she liked being cuddled, and the reason for not putting weight on her feet could be from her being in a cast for 3 months. (She had surgery to correct hip dysplasia and was out of the spica cast for 4 months at that time) So the pediatrician decided that my concerns about autism were unfounded.

I contacted EI when my daughter was 18 months because in my gut I just knew there was something going on, and it's honestly the best thing I ever did.

With the guidance of EI my daughter who is 28 months, now walks, points, has improved eye contact (still not great) and has over a 300 word vocabulary, and is putting 2 and 3 word sentences together. She still doesn't know her name or recognize herself in a mirror, but we are working towards that and I know she will get there.

I honestly don't know where we would be without EI!!!!

They get bored of certain words and like to learn new ones. Maybe try teaching her some new words.

@Emily your advice is so very much appreciated. Thank you. ? I had no idea one had to come before the other. I thought they would happen at the same time.

Our speech therapist for my son always highlighted how important nonverbal communication was as a stepping stone to verbal communication. Our brains have to wire up in a particular way to develop speech and one of the stepping stones is grasping the concept of doing something with the intent of sending a message that can be understood by someone else. So pointing at a cup because you want it and then being given it etc.
Always encourage verbal communication but the best place to start is with skills like pointing. It sounds silly but when I read into it, it really made a lot of sense.

I know you weren’t actually asking for advice on helping her communication but I just wanted to share ?
My son was nonverbal until a month before he turned 3, nonverbal communication didnt come naturally to him and teaching him to point changed his entire world.

Not sure if it's connected but a few days ago she started occasionally walking weird. It seems intentional. SO let's telling me she's just trying out new things.

She'll turn her head to the side, force her eyes forward and try and walk. It only ever lasts a few minutes before going back to her regular happy self.

SO and i have had concerns in the past about other things that armed really strange and the doctor has continued to assure us that she's fine.

@Emily she doesn't point. I've tried showing her. I'll put up one finger and she'll copy but has never pointed to something. For waving, she'll only do it if i 'start it' for her by taking her arm and waning it for her then she'll wave.

I notice when dd who is 20 months learns a new word she tends to say it non stop before saying all of her old words. She knows TONS of words but right now she mostly just says Hi and Oh no.

This can go both ways. She is still really little and has time for her speech to develop so at 15 months I wouldn’t be concerned but I would be keeping a watchful eye which you seem to be doing already!
Mention it to your doctor/health visitor if it continues.

Does she use gestures like pointing and waving? Or nodding yes/no?

my daughter does this. she picks and chooses what she says.

Definitely normal. My little guy is 18 months now and said mama dada and hiya for a while (like yourself not directed just babbling) and then he stopped at around the same age as your daughter. And then started again about 3 weeks to a month later. He now says mama, dada, nana + baba direct.Hiya on the phone... And today he said Spider for the first time. Nothing to worry about just keep encouraging her x
