Sounds like youre letting your child control you too! Hes 18mths just because he CAN walk/talk doesnt mean he has to! Stick him in a buggy for walk- so what if he throws a tantrum! Its what little kids do- youre his parent,you must weather the tantrum and tell him no- he needs to learn hes to do as you want,not other way round!-(trust me ive brought up 7!) that aside yes i would meet your mum for just a walk- as Wildswan16 says- youre allowed out for excercise- just no touching- and your boy would probably need to be in his buggy anyway now,or he'd be touching everywhere& everything when& if you are out- you also sound as if you are letting your husband control you too- and surely he isnt at work 24/7- cant he watch his own child at SOME point so you could have a (2metre apart) walk with your mother? Even if its at teatime?or on a day off? youre doing as everyone else wants,but you clearly do miss your mum too,to a certain extent.go alone at first, chat through her window- or walk with her,but not near her.But you need to take control of your own life,starting with making your child go in his buggy if you need him to, he is 1.5yrs(18months) not 21 years! 
The media are already after Andy!
