What trousers does a 3 yo wear in winter?

[santasknackered]

My son is 3.5 and complains about being cold when we are on the way to nursery (though he insists on only wearing shorts and t-shirt round the house!). We walk most places as we live in London. He has a warm coat, hat etc. He wears tracksuit trousers everyday as they are easy for him to dress himself and for getting dirty at nursery.

Not sure what else I can do to keep him warm and if other trousers would be better? What trousers does your 3yo wear and are they warm enough?

They are cheap multipack ones from Next but are there better quality warmer brands?

If just while walking places then a pair of fleece lined waterproof trousers or all in one puddle suit to wear over his clothes? That won’t affect him being able to go to the toilet easily at nursery and he can also wear there to stay warm playing outside. Jojomamanbebe do good ones or muddy puddles, also saw some in Tesco . Otherwise thermals under joggers but these are more of a pain to wear

Are there any issues at nursery? Might be worth talking to the staff. My grandson says his knee hurts to get a day off.
