I have a maxi cost axiss which has worked quite well for the past 2 years. In the past few months I feel the harness has grown to be too tight for DS. It is extended to max and its hard to snap the harness closed. He does whine and wince from time to time depending on how many clothes he has on.
He has always been a large/tall baby (is 93cms and 17kgs) he is 2.6 yrs old now. Axiss was a blessing with a heavy child..but I am nt to sure how to make space for him in the seat.
What should I do? What comes next? Do we need to wait till he is 3 to get a booster? Are there extensions available to a harness? Was this bound to happen with thick winter coat on him?
Any advice will be highly appreciated! Thanks
