DS is three months, he’ll be 14 weeks this Friday but has almost outgrown his carrycot, and I worry he’ll start hurting his feet when kicking as he pretty much touches the bottom now! We have the Urbo2 pram from Mamas & Papas, and I’ve tried him in the pushchair attachment this morning which he seems to love! I’m just worried he’s too young as he can’t support his head 100% yet. (It does fully recline though so we’d have it pretty flat initially.) Picture attached for thoughts 
Thanks!!
