Hi, I'm looking to buy a lightweight buggy. DD is 4.5mths old and we live in house which is elevated and has 20 steps up to it. She is getting too heavy for me to carry up and down along with her pram plus she is nosey and doesn't want to lie back in pram anymore. Looking for so,etching very light but also comfortable for DD and preferably parent facing option. Don't ask much do I? Any suggestions?
