Just wondering how others entertain / stimulate a 4 month old she's actually 15 weeks but close enough . I don't like putting her in her bouncer too much so I also lay her on her play mat , I play with her to make her laugh . She isnt reaching grabbing for things yet . I feel very guilty if I leave her down to get things done I feel I should be stimulating her more ?? I also bought her a little otter that plays music and breaths but maybe a bit young doesn't pass any seem on him yet but leave him there playing music . I e also started butting her in a carrier for short periods around the house to try get her used to it .
