Toilet seat recommendations

[Kay3011]

Looking for recommendations on seats to go on the toilet for my nearly 3 year old.
My LB likes to get on the toilet himself so we got the toilet seat from Aldi with the steps but finding it doesn't quite fit right and that pee escapes between the seat and the toilet all the time! Are there any others that anyone uses that work better?

These are brilliant, they will lift on and off but are really secure, no horrible wobbling. Easy to clean too. We had one upstairs and one down.

I have recently fitted a 'family toilet seat' and it's really good - basically a normal toilet seat with a smaller child seat under the lid that you can pull down for them to sit on. An advantage is that it's not as high up as most of the seats you put on top. We just have a normal step stool in front to climb up on.

I second the ‘family toilet seat’. Really good
