DD is 2 years and 8 months (turns 3 in April). She is still in nappies to leave the house and overnight. During the day time when at home, we remove the nappy and have her running around bare from waist down, and leave her potty in an accessible place where she's playing. She's usually really good at running to the potty for a wee, saying "oh no wee wee!" before she starts to run to it, so she's clearly recognising the signs of needing to go, which is good. She will ask for a nappy if she needs to poo, she's pooed on the potty maybe once or twice in recent months but it's taken her by surprise and frightened her a bit, so she's slightly regressed and asks for a nappy if she needs a poo. I'm not too concerned about that part.
I suppose why I'm posting is, I have mum friends whose little ones are a few months older (so one as an example turns 3 in January), and they are in knickers when leaving the house (and have been since the summer), so then they were approx around DD's age now. We all met at the park back in the summer and I felt a little embarrassed that my DD was wearing her nappy (at that time only 2 years and 4 months admittedly), while the other toddlers were wearing knickers and telling their mums when they needed to wee and being taken to the toilet etc.
Basically what I'm saying is, I'm concerned my DD "behind" with this compared to her peers? Granted, the little girl who was most potty trained when we met in the summer is 3 months older than DD - but I don't think that's a huge difference? Shall I just bite the bullet and take DD out in knickers and be prepared for accidents? I haven't even tried knickers in the house yet - we just have her naked from the waist down and she goes on the potty.
Nursery are saying she has asked a couple times to sit on the "big girl toilet", seemingly copying the others who are already 3. They said a handful of times she's done a wee when on the toilet and her nappy has been dry, and at other times she she hasn't done a wee but has just wanted to sit on the toilet like the other girls and boys.
We are invited to a birthday party for the little girl who is toilet trained and turns 3 in January, and I feel a bit embarrassed to take DD whilst still wearing nappies (this is probably my own issue and not fair to DD).
How do I progress this? What's the next step? Any advice appreciated. Thank you!
